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.

Seven Things You Need to Know When Importing Products from China to the U.S.

Seven Things You Need to Know When Importing Products from China to the U.S.

  1. Service Standards for U.S. Cargo

    Goods destined for the United States require meticulous service, and the services after arrival at the port are also very important. If no customs brokerage proceeds within 15 days after the goods arrive at the port, the goods will enter the G.O. warehouse, and the fee standards of the G.O. warehouse are very high.

  2. Agency Qualification Review

    For the U.S. route, besides the shipping companies, all legitimate freight forwarders engaged in the U.S. line must own a freight forwarding company registered in the U.S. (FMC) and have an official NVOCC code, otherwise, they cannot receive corresponding legal protection if any problems occur during the transportation in the U.S. Not all first-level freight forwarders are FMC registered members, so it is crucial to confirm in advance.

  3. Detailed Regulations

    1. Confirming the specific transportation destination in U.S. trade is very important, as many clients have different warehouses all over the U.S., and it is crucial to finally confirm their FINAL DESTINATION during transportation. Especially since there are many places with the same name in the U.S., like Washington, which has four or five, it is very likely to send the wrong goods if the client does not have the week name and zip code. The vast land and sparse population in the U.S. mean that trailer fees are often more than a thousand dollars, so it is most critical to clarify and allocate responsibilities with the client.
    2. Large U.S. customers have many requirements for logistics fee services provided by suppliers. A. Customers often have sectional requirements for loading containers, which is especially important for goods sold to foreign supermarkets (such as the order of placement, quantity requirements, and documents included in the container). B. Deliver on time as per customer requirements. It is crucial to track the dynamics of the container as many foreign clients will require the goods to arrive at the port before a specific time (SHIPPING PERIOD), and delays by the factory may cause substantial fines abroad. Tracking the logistics goods is also very key. C. Provide accurate and timely documents for customs clearance abroad, generally speaking, foreign customs clearance can be done 7 days before the ship arrives, to avoid possible DETENTION and DEMURRAGE, many times it is often because of the delay of documents that causes foreign detention fees.
    3. Port overdue pickup fees and demurrage charges: The company charges them, and for large customers, more free use dates can be given. Port demurrage fees: Charged by the shipping company’s terminal, and they vary from one terminal to another.
  4. Freight Rates

    All freight forwarding companies on the U.S. line use contracted prices, but not every freight forwarding company has the price of the U.S. line; only those with strong capabilities can sign the U.S. line prices directly with various shipping companies. Because there is an organization in the United States called FMC, its role is to adjust the transportation prices of all shipping companies in the United States to protect the interests of American customers.

  5. Weight Limitations

    Here, the weight limit = the weight of the goods + the weight of the container. The requirements for the weight of goods to the U.S. line are very strict, mainly affected by the road weight limit to inland points in the U.S., typically small containers 17.3 tons, and tall high containers 19.5 tons. However, different ports have different weight limits, and if it is necessary to transport overweight goods to inland points in the U.S. as per customer requirements, there are generally three ways to handle it:

    1. Under-declare booking data, customs data, and manifest data to make the weight acceptable for shipment. Disadvantage: If checked and weighed on U.S. roads, there could be heavy penalties.
    2. Offload at the base port, then redistribute and transport the overweight part separately. Disadvantage: If the inland point for transfer is far, the cost is high.
    3. Some shipping companies can transfer directly from the base port terminal to the inland point by rail in the U.S., which can reach the inland point. If it needs to be delivered to the door point, it can be transported locally with a three-axle heavy chassis, and this part of the trailer fee is about 30% more expensive than the general trailer fee. Difficulty: Finding such a shipping company, inquiring about the inland point with this service, and finally having a good local agent to arrange the transfer of the overweight trailer. Generally, the first method is not recommended. Due to regulatory issues, there is a relatively high chance of being checked and weighed on U.S. roads, and taking chances might lead to more loss than gain.
  6. Customs Clearance Rules

    1. U.S. Customs receives AMS declaration data from the exporting country after the ship departs.
    2. Local freight forwarding companies or customs brokers in the U.S. must receive the necessary import documents and arrival notices from the shipping company one week before the ship arrives.
    3. Apply for import customs declaration and inspection with U.S. Customs, and submit documents to the destination port shipping company to request cargo release.
    4. Provide the container release proof to the consignee’s trucking company or have it transported to the designated warehouse by the local agent.
    5. In the TO DOOR situation, the operation process of delivering goods must be done when the consignee is ready. The trucking company only provides two hours of loading and unloading time at the warehouse, with additional hours charged. Door delivery must not exceed the U.S. road weight limit.
  7. Import Documentation Requirements

    The global H.S. CODE is uniform, but to confirm the taxes and fees abroad, the most accurate product name description must be provided. The determination of tariffs in the United States is one of the most troublesome matters in the world: if there are DDP customers, the most accurate product name and H.S. CODE must be provided, and customers who receive shoes need to send sample shoes abroad for confirmation.

  2. Ink Printing (Offset Printing)

    : This step involves applying colored designs, logos, and text onto the tubes using offset printing techniques, which allows for high-quality, detailed images.

  3. Silk Screening

    : An additional method for applying graphics to the tube, silk screening is used for vibrant, opaque colors and can apply thicker layers of ink than offset printing.

  4. Hot Stamping (Foil Stamping)

    : A decorative process that applies metallic or pigmented foil onto the tube for a shiny, reflective effect. It’s commonly used for logos, accents, or text to add a premium look.

  5. Labeling

    : Applying labels to the tube, either by wrapping pre-printed labels around it or by directly adhering them to the tube surface. Labels can provide additional information, branding, or decoration.

  6. Nozzle Insertion

    : Attaching the nozzle or applicator to the tube, which can vary in design based on the product’s application method (e.g., narrow tip for precision or wider openings for thicker creams).

  7. Capping

    : Screwing or pressing the cap onto the tube. Caps can vary widely in design, from simple screw caps to flip-top, twist-off, or pump-action caps, depending on the product requirements.

  8. Packaging

    : The final step involves packaging the finished tubes for shipping and retail. This can include placing tubes into boxes, sealing, and labeling the packages for distribution.

Insightful Comparison: PET Bottles vs. PP Bottles in the Cosmetic Industry

Insightful Comparison: PET Bottles vs. PP Bottles in the Cosmetic Industry

In the vibrant world of cosmetics, the decision between PET (Polyethylene Terephthalate) and PP (Polypropylene) bottles requires a deep understanding of their unique characteristics and functions. Drawing on our expertise in plastics, I will explore the disparities between these two materials through a comprehensive analysis of four key factors: barrier properties, transparency, heat resistance, and specific applications within the cosmetics industry.

Barrier Properties Explored

First and foremost, PET bottles have gained prominence for their exceptional barrier properties, effectively warding off oxygen, water vapor, and carbon dioxide. This feature renders them ideal for products that are sensitive to oxidation or moisture. Therefore, cosmetics containing fragile natural ingredients prone to degradation can benefit from PET bottles, which significantly extend their shelf life.

In contrast, PP bottles exhibit good resistance against moisture but comparatively lower barrier properties against gases such as oxygen. Consequently, products in need of stringent protection from oxidation may not find PP bottles as suitable.

Delving into Transparency

Moving on to transparency, PET bottles boast a visually stunning attribute with their crystal-clear appearance. Their impeccable visibility and gloss make them particularly appealing for the cosmetics industry, where product appearance and branding play a pivotal role.

On the other hand, PP bottles possess a naturally translucent to opaque appearance. While it is possible to manufacture transparent PP bottles, they generally lack the glass-like clarity exhibited by PET bottles. This aspect can serve as a drawback for premium cosmetic products that value clarity and product visibility above all else.

Unveiling Heat Resistance

When it comes to heat resistance, PET bottles can withstand moderate temperatures of approximately 60°C (140°F). This characteristic makes them suitable for a wide range of cosmetic products; however, they may not be the best choice for items requiring high-temperature sterilization or exposure to hot environments.

Conversely, PP bottles excel in heat resistance, enduring temperatures of up to approximately 100°C (212°F). This higher tolerance renders them more suitable for cosmetics that might undergo high-temperature processes or require storage in hot conditions.

Applications within the Cosmetics Industry

Finally, PET bottles find extensive usage in the cosmetics industry for various products, including lotions, serums, and liquid foundations. Their aesthetic appeal, combined with their commendable barrier properties, positions them as a preferred option for premium cosmetics, where product preservation and quality are paramount.

In summary, the choice between PET and PP bottles in the cosmetic industry demands a discerning examination of their distinct attributes. While PET bottles offer excellent barrier properties, unparalleled transparency, and moderate heat resistance, PP bottles showcase good resistance to moisture, solid heat resistance, and a range of applications within cosmetics.

Find High Quality Plastic Bottle Container in China Manufacturer

The Dawn of the Plastic Generation

In the 1980s, China began a significant transformation in its packaging industry by importing advanced plastic bottle production lines from abroad. This era marked the start of the “plastic generation,” where plastic bottles rapidly became prevalent in packaging. These bottles, crafted from non-toxic polymers such as High-Density Polyethylene (HDPE), Polyethylene Terephthalate (PET), Polypropylene (PP), and Polycarbonate (PC), were produced using cutting-edge plastic molding technology. They were designed to contain a variety of liquids and solids, including capsules, tablets, powders, granules, plastic pills, and oral liquids.

I. The Utilization of Plastic Bottles

Widespread Use in Domestic Markets

Currently, in China’s domestic market, a vast array of products, including pharmaceuticals, nutritional supplements, food, and beverages, are packaged in plastic bottles. These are commonly seen in pharmacies and supermarkets. Medicines and health supplements are mainly packaged in PET and HDPE bottles, while beverages predominantly use PET bottles. Daily necessities like shampoo and shower gel are more frequently packaged in HDPE bottles.

The primary advantages of plastic bottles are their lightweight nature, resistance to breaking, cleanliness, and aesthetic appeal. Technical indicators and extensive data show their excellent chemical resistance and low moisture permeability, effectively protecting products from moisture damage within their expiration period.

II. Principles for Selecting Plastic Bottles

Ensuring Quality and Safety

  1. Material Safety: Regardless of the material chosen for plastic bottles, they must meet non-toxic and odorless standards. Given the variety of available raw materials, comprehensive performance is considered in the selection process. HDPE and PET bottles are preferred for pharmaceuticals, with transparent PET bottles being a better option for visibility. Amber-colored PET bottles are chosen for higher barrier properties and opacity.
  2. Sealing and Permeability: The sealability of the bottles and lids and their vapor permeability are crucial technical indicators, significantly affecting the stability of the packaged products.
  3. Quality Standards: Product quality can be analyzed and judged based on the quality standards of the manufacturing facility.
  4. Quality Assurance Systems: Supplier audits have become an essential part of the procurement process for plastic bottles. These audits provide a clear understanding of the manufacturer’s facilities, technical equipment, and overall quality level, allowing for a comprehensive and accurate evaluation.
  5. Regulations on Recycled Materials: For packaging pharmaceuticals, nutritional supplements, food, and beverages, the use of recycled materials is prohibited. The Ministry of Health’s regulations on the hygiene management of food plastic products and raw materials stipulate, “Processing of plastic utensils, containers, and food packaging materials must not involve recycled plastics.” This regulation was issued on November 26, 1990.

The Omnipresence of Plastic Bottles

Plastic bottles are now ubiquitous in daily life, closely linked to everyday activities. Many plastic bottles are reusable, and recycled plastics can be processed into other products. However, driven by profit, some companies may opt for low-cost recycled materials for bottle production, raising concerns among consumers. Vigilance is advised if impurities are found in the bottles or if the clarity of transparent bottles is compromised.

Our factory has been producing plastic bottles for over a decade, using 100% new raw materials, adhering to quality standards, and maintaining our quality assurance system. We primarily produce plastic beverage and cosmetic bottles, which are closely related to consumer health. Unless specifically requested, we also use 100% pure materials for larger plastic containers like laundry detergent bottles.
