What manufacturing process are shampoo bottles made by

Everyone uses shampoo, but most people may only pay attention to the shampoo products. However, some of them may also keep an eye on the plastic container holding the shampoo. They may wonder what the manufacturing process of plastic containers is. In this article, you can better understand the plastic container holding the shampoo and its manufacturing process.

 

PET bottle

PET material is safe, has no plasticizer, and is sufficiently flexible, with a high transparency grade. Many colors are available for PET bottles, like transparent, semi-transparent, and solid colors. Some brands prefer the PET bottle to be strong and hard to squeeze, while some products need to be squeezable, such as hair conditioners. How is PET material a safe material? You can see many drinking bottles using PET material; it is good evidence. But PET material cannot be put into a high-temperature container; its heat-resistant temperature is about 70℃, so PET bottles can only be stored at room temperature or cold beverages. For shampoo, there is no worry to use PET bottle at all.

 

PE bottle

PE plastic is one of the most commonly used materials for shampoo; its natural color is opaque and can hold some large-capacity shampoo products. Therefore, PE bottles can resist the erosion of many chemical products; they are widely used for storing cosmetics, detergents, and more. Moreover, PE bottles are cheaper than PET bottles and incompatible with plasticizers. It can also be used as a material for food preservation, so it is non-toxic.

 

PP bottle

PP material is milky white and translucent, which looks like the milky white of body milk, not pure white or transparent.PP bottles are soft and squeezable, but the transparency is not as good as PET bottles, so some opaque shampoo bottles also prefer to use PP bottles, such as hair dye products and hydrogen peroxides. For colored PP bottles, it is made by adding a color master, which means adding the color master in mixing material. PP plastic products are safe and non-toxic, too, and there is no plasticizer.

The above paragraphs have explained the three main plastic materials for shampoo bottles: PET, PP, and PP. The following is the manufacturing process of these three types of plastic materials.

The manufacturing process of PET bottles and PP bottles typically have two methods:

one is a step process, and the other is a two-step process. Now, many PET bottles are produced by a two-step process: Use the injection machine to cast a preform(like a tube), then put this bottle preform into a bottle blowing mold, blow it to match the bottle mold perfectly, and the preform tube will be expanded into the mold shape, take it off and make it cool down.

 

The ingredients of shampoo are mainly used for increasing the glossiness of hair and to sterilize, clean, and foam, which will not be harmful to PE bottles, and PE material is not soluble in water, with low water absorption, it is very safe to use PE bottle too.

PE bottles are usually manufactured by hollow extrusion blow molding process, which is to melt and plasticize the PE material by the extruder, extrude the tubular parison, and then place the parison in the blow molding mold, blow it with compressed air, and cool the PE bottle of the exact shape of the mold obtained.

What are the different methods of extrusion blow molding?

What are the different methods of extrusion blow molding?

What are their advantages and disadvantages?

Based on the different ways of discharging in extrusion blow molding, it can be divided into two molding processes: direct extrusion blow molding and extrusion-storage-pressure blow molding.

Direct extrusion blow molding. This method directly extrudes a parison from the extruder.

Its advantages include: simple structure of molding equipment and mold, less investment, low production cost of products, easy operation, suitable for thin-walled, complex-shaped, and irregular products, and suitable for blow molding of various plastics.

It is currently the basic molding method commonly adopted by small enterprises in our country. Its disadvantage is: since the extrusion speed of the parison is slow, a larger parison will sag due to its own weight, causing the parison wall to be uneven and produce internal stress, thereby leading to uneven thickness of the blow molded product.

Therefore, this method is suitable for the production of small containers. As for the problem of post-processing of plastic parts to remove flash, as the level of automation increases, manual operations to remove flash are decreasing, and product quality is getting higher.

Extrusion-storage-pressure blow molding. Its production process involves extruding the plastic melt into a storage cylinder. When the material in the storage cylinder reaches a certain amount, it is pressed out by a hydraulic cylinder in a measured and pressurized way, and a hollow container consistent with the shape of the mold cavity wall is obtained through the machine head.

The parisons produced by this process have the following advantages:

Firstly, using the storage device, larger containers can be produced with smaller equipment. For example, a medium 65 extruder can produce a 50L barrel.

Secondly, the plastic melt is rapidly pressed out by the pressure system, allowing for the required length of the parison to be obtained in a short time, greatly reducing the sagging phenomenon of the parison, thereby ensuring product wall thickness uniformity.

The disadvantages are: due to the addition of a storage and pressure system, the equipment structure is complex. The design and maintenance of the hydraulic system bring some difficulties to production, and the equipment investment is larger than direct extrusion blow molding process.

Can cosmetics still be used if they are left in a car?

Can cosmetics still be used if they are left in a car?

If cosmetics are left in a car for too long, it is not recommended to use them because skincare products are sealed in containers. When placed in a closed car space where the temperature rises, some components of the cosmetics can undergo changes.

Skincare products should ideally be stored in a cool and dry place under normal pressure and humidity. After use, it is important to tightly close the bottle cap. Additionally, it is not advisable to store cosmetics in the bathroom or outdoors, as the high temperature and humidity in these environments can cause mold growth and affect the safety of the products.

What can be done to remedy skincare products affected by high temperatures?

There is no way to remedy skincare products once they have been affected by high temperatures. Therefore, it is important to store skincare products in a place away from direct sunlight and at an appropriate temperature.

Although skincare products undergo high-temperature stages during development, it is still recommended not to store them in high-temperature areas, regardless of whether the packaging has been opened or not. Especially in summer, when purchasing skincare products, some delivery boxes are often exposed to direct sunlight, which can affect the active ingredients inside the products, particularly for serums and similar items. Furthermore, some people tend to store all their skincare and cosmetic products on the bathroom vanity, but this is not advisable because the steam from showers can penetrate the products and also affect their effectiveness.

Sealing layer in the aluminum foil sealing liner

The heat sealing property of the sealing layer:

The primary condition for aluminum foil sealing liner to fuse and seal with the bottle mouth is that the sealing layer of the aluminum foil gasket must have heat sealing property. The heat sealing property of plastic refers to the thermal bonding property that the plastic has with itself or other types of plastic after being heated to a molten state.

The commonly used films with heat sealing layers are: PE (including HDPE, LLDPE, LDPE, etc.), CPP, modified PET, and other polymer resins (such as hot melt adhesive).aluminum foil seal

Correspondence between sealing layer materials and bottle materials:

When using aluminum foil sealing gaskets, it is important to note that the material used for the sealing layer must correspond to the bottle material. The corresponding relationship between them is as follows: Sealing layer material Bottle material PE heat sealing film LDPE, HDPE CPP heat sealing film PP Modified PET heat sealing film PET Hot melt adhesive LDPE, HDPE, PP, PET, glass, ceramics

Note: Aluminum foil gaskets with hot melt adhesive as the sealing layer can seal bottles of various materials, but the sealed object cannot be volatile or corrosive. If it is a liquid substance, it cannot be sealed in a hot filling environment.

Tear ability of sealing layer materials:

Due to the continuous demand for user-friendly packaging design, the sealing layer materials of aluminum foil sealing gaskets have also been continuously improved. In recent years, heat sealing material manufacturers have developed easy-to-tear films of different materials, which makes it so that the bottle mouth does not leave any aluminum foil or sealing layer material when the aluminum foil gasket is torn open after sealing. Examples of such easy-to-tear heat sealing films include CPP (PE) easy-to-tear heat sealing film, PET easy-to-tear heat sealing film, and other high-polymer material heat films. However, these easy-to-tear heat sealing films can usually only package products that are non-volatile and solvent-free.

A good packaging container for refill——airless pump bottles

A good packaging container for refill-airless pump bottles

Airless pump packaging bottles are indeed useful. They effectively prevent air and bacteria from entering the bottle. By removing the air inside the airless pump packaging bottle, the exposed surface area of the product is reduced, which slows down the oxidation process and extends the product’s shelf life.

One of the main advantages of airless pump packaging bottles is that they prevent product evaporation. For cosmetics or skincare products with volatile ingredients, such as essential oils or perfumes, airless pump packaging bottles can effectively reduce the loss of these components. Additionally, the airless pump environment prevents oxygen from affecting the product, thereby maintaining its original texture and efficacy and avoiding texture changes or diminished effectiveness.

Another advantage of airless pump packaging bottles is that they allow for the transfer of large volumes of cosmetics or skincare products into smaller containers. This is particularly useful for carrying personal care products during travel or outings. You can transfer the desired amount into smaller bottles, making them convenient to carry and use without having to carry the entire large bottle. This not only saves space but also reduces the weight of your luggage.

Furthermore, airless pump packaging bottles help reduce waste. By controlling the amount used each time, you can better manage the product and avoid excessive usage that leads to waste. The airless pump environment also reduces the product’s exposure to air, lowering the risk of bacterial contamination and minimizing the possibility of pollution.

Airless pump packaging bottles are practical and beneficial for refilling lotion/perfume/serum/liquid. They protect the quality and efficacy of products, extend shelf life, and provide convenient portability and usability. Whether for travel convenience or waste reduction, airless pump packaging bottles are worth considering.

PET bottle blow molding production process

PET blow-molded bottles can be divided into two categories: one is pressurized bottles, such as bottles filled with carbonated drinks; the other is unpressurized bottles, such as bottles filled with water, tea, oil, and other beverages. Tea beverage bottles are modified PET bottles or composite bottles of PET and thermoplastic aromatic polyester blended with polyethylene naphthalate (PEN), which belong to the hot bottles category and can withstand temperatures above 80℃. Water bottles belong to the cold bottles category and have no requirement for heat resistance. The molding process for hot and cold bottles is similar. Today, we will mainly discuss the molding process of pressurized beverage bottles in cold bottles.

1, Equipment

With the continuous advancement of technology and the scale of production, the automation level of PET blow molding machines has become increasingly higher, and the production efficiency has also increased. The production capacity of equipment has been continuously improved, from producing thousands of bottles per hour in the past to producing tens of thousands of bottles per hour now. The operation has also developed from the previous manual button operation to the current full computer control, greatly reducing the difficulty of process operation and increasing the stability of the process.

2, Blow-molding process

The important factors affecting the PET bottle blow-molding process include the preform, heating, pre-blowing, mold, and environment, etc.

3, Preform

When preparing blow-molded bottles, PET chips are first injection molded into preforms, which require that the proportion of recycled materials for secondary use should not be too high (less than 5%), the number of recycling times should not exceed two times, and the molecular weight and viscosity should not be too low (molecular weight 31,000-50,000, intrinsic viscosity 0.78-0.85 cm3/g). The injection-molded preforms need to be stored for more than 48 hours before use. Preforms that have not been used after heating must be stored for more than 48 hours before being reheated for use. The storage time of preforms cannot exceed six months.

The quality of preforms depends largely on the quality of PET materials. Materials that are easy to blow and shape should be selected, and a reasonable preform molding process should be developed. Experiments have shown that preforms made from PET materials with the same viscosity, imported raw materials are easier to blow and shape than domestic materials, and preforms from the same batch, but with different production dates, may also have significant differences in blow molding process. The quality of the preform determines the difficulty of the blow-molding process, and the requirements for the preform are purity, transparency, no impurities, no off-color, and appropriate injection point length and peripheral halo.

4, Heating

The preform is heated in a heating oven, the temperature of which is manually set and automatically adjusted. Far-infrared lamps in the oven radiate the preform with far-infrared rays, and the bottom fan circulates heat in the oven, making the temperature inside the oven uniform. The preform moves forward in the oven while rotating, making the preform wall evenly heated.

The arrangement of the lamps in the oven is generally in the shape of a “zone” from top to bottom, with more lamps at both ends and fewer in the middle. The oven temperature is controlled by the number of lamps opened, the overall temperature setting, the oven power, and the heating ratio of each section. The opening of the lamps should be adjusted in combination with the pre-blowing bottle.

To make the oven work better, it is important to adjust the height and cooling plate properly. If the adjustment is not appropriate, defects such as swollen bottle mouths.

The production process of pharmaceutical plastic bottle caps

The production and processing process of pharmaceutical plastic bottle caps is similar to the requirements of the bottle body, except that the main raw material for the bottle body is blow molding grade, while the main raw material for the bottle cap is injection molding grade. The production process of pharmaceutical plastic bottle caps is injection molding.

The main process of this technology is:

Firstly, material addition. The material mixture is mainly transported to the injection molding machine hopper by pipelines. After the machine is opened, the material in the hopper enters the feeding barrel, completing the process of feeding the machine.

Secondly, plasticization is the process of heating the plastic material mixture that enters the feeding barrel into a flowable state with good plasticity. The requirement is that the plastic should reach the specified forming temperature before entering the mold cavity, and provide a sufficient amount of molten plastic within the specified time.

Thirdly, injection. The plasticized melt is injected into the mold under the pushing pressure of the screw (injection process). When the molten material enters the injection mold cavity, it needs to pass through the nozzle, main (branch) runner, and gate, and the resistance is high. The injection pressure loss is 30%-70%, so the process requires sufficient injection pressure to ensure complete filling. Then comes the molding stage, which includes four steps: mold release, compaction, backflow, and gate solidification. The plastic melt injected into the mold cavity is cooled and shaped into a plastic cap.

Fourthly, cooling and demolding. It mainly refers to the stage from the complete freezing of the plastic at the gate to the stage where the cap is released from the mold. Demolding can be achieved through strong demolding and rotary demolding.

Why nicotinamide is so popular?

Why nicotinamide is so popular?

Nicotinamide, also known as niacinamide, is a popular ingredient in many skincare products due to its numerous benefits for the skin. Here are some reasons why nicotinamide is so popular:

Improves skin barrier function: Nicotinamide helps to strengthen the skin’s natural barrier, which can become compromised due to environmental factors, aging, and certain skincare products. A stronger skin barrier can help to retain moisture and prevent dehydration, as well as protect against environmental stressors and irritants.

Reduces inflammation: Nicotinamide has anti-inflammatory properties, which can help to reduce redness and inflammation in the skin. This can be especially beneficial for those with sensitive or acne-prone skin.

Brightens skin: Nicotinamide can help to brighten the skin and reduce the appearance of hyperpigmentation and dark spots. It does this by inhibiting the transfer of pigment to skin cells, which can lead to a more even skin tone.

Anti-aging benefits: Nicotinamide has been shown to have anti-aging benefits for the skin. It can help to reduce the appearance of fine lines and wrinkles, as well as improve skin elasticity and firmness.

Safe and well-tolerated: Nicotinamide is generally considered safe and well-tolerated, even for those with sensitive skin. It is also non-irritating and non-sensitizing, making it a popular choice for those with reactive skin.
