How to Choose the Right PE Cosmetic Soft Tube

Cosmetic tubes, including those made from Polyethylene (PE), have revolutionized packaging in the cosmetics and pharmaceutical industries. Known for their hygiene, convenience, vibrant surface colors, and economic advantages, PE tubes maintain an excellent appearance even after intense squeezing. They are widely used for packaging paste-like cosmetic products such as facial cleansers, conditioners, hair dyes, toothpaste, and topical ointments in the medical sector.

1, Material and Type Classification of Cosmetic Tubes

Cosmetic tubes generally comprise the tube itself plus a cap, with the tubes frequently made from PE plastic. Alternatives include laminated (aluminum plastic) tubes, all-aluminum tubes, and eco-friendly paper plastic tubes.

• All-Plastic Tubes

  : Entirely made from PE, these tubes are extruded, cut, and then printed with various techniques like ink printing, silk screening, and hot stamping. They can be categorized by the shape of the tube head (round, flat, oval) and the type of seal (straight, diagonal, custom shapes).

• Laminated Tubes

  : Featuring an inner layer of PE and an outer layer of aluminum, these tubes are cut and then rolled. Options for the tube head and seal are similar to those of all-plastic tubes.

• \

• All-Aluminum Tubes

  : Made entirely from recyclable aluminum, offering an eco-friendly choice. Their downside is susceptibility to deformation, making them ideal for high-end product packaging where cosmetic appearance is paramount.

2, Classification by Product Thickness

Tubes can be single-layer, double-layer, or five-layer, offering varying degrees of pressure resistance, permeation prevention, and tactile feel. Single-layer tubes are thinner, double-layer tubes are more common, and five-layer tubes are premium, featuring an outer layer, inner layer, two adhesive layers, and a barrier layer for exceptional gas barrier properties.

3, Tube Shapes

Available shapes include round, oval, flat, and super flat, catering to different aesthetic and functional requirements.

4, Tube Diameter and Height

Tube diameters range from 13# to 60#, with different lengths indicating capacity from 3ml to 360ml. For visual harmony, tubes under 60ml typically use diameters under 35#, while those for 100ml and 150ml use 35# to 45#, and larger capacities require diameters above 45#.

5, Tube Caps

Caps vary widely, including flat, round, tall, flip-top, super flat, double-layer, spherical, and lipstick caps, with options for decorative processes like gold or silver edging, colored caps, transparency, spray oil, and electroplating. Pointed and lipstick caps usually come with an inner plug.

6, Manufacturing Process

• Tube Body

  : Options include colored, transparent, matte or glossy finishes, with matte appearing elegant but prone to dirt. Tube colors can be directly integrated into the plastic or achieved through extensive printing, distinguishable by the color at the cut end of the tube. High-quality ink is necessary to prevent peeling and cracking under stress.

• Printing

  : Techniques include silk screening (for specific colors and small blocks, similar to plastic bottle printing) and ink printing (for larger, more colorful designs, commonly used in daily chemical lines), along with options for gold and silver hot stamping.

7, Specific Tube Production Process

The manufacturing of cosmetic tubes involves a sequence of precise and specialized steps to ensure product quality, functionality, and appearance. Here’s an overview of the typical production process for cosmetic tubes:

1. Tube Extrusion

   : The process begins with extruding the tube material, typically polyethylene (PE) or a combination of materials for laminated tubes, into the desired shape and length.

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

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.

Airless Pump Packaging Innovation

Airless pump packaging literally means that formulas are contained in an oxygen-free state for maximum protection.

The airless pump packaging ensures a formula is never in contact with air, until the moment it is used and makes it ideal for protecting products from external contamination such as air-contact, touch by hands, evaporation and any external matters.

Airless system reduces the need for artificial preservatives and extends shelf life.

For high-value products, or those with active ingredients, it is important that a precise amount is applied with each use—airless systems dispense an exact dosage with each stroke.

And compared to most other types of packaging, airless packs have a high restitution rate—waste is avoided, as nearly all of the formula is used.

In order to keep tracking the trend, Canvard Packaging has various airless pump bottles design, welcome to get a quotation.

What is an airless pump bottle

Airless pump bottle refers to a container that can isolate the air from the outside temperature or a container that isolates external bacteria.

Its contents can be completely isolated from the air, preventing the product from being oxidized and deteriorating due to contact with the air, breeding bacteria, and improving the product grade with its high-tech design.

The airless pump bottle commonly used in the market is composed of a cylindrical or ellipsoid container with a piston placed at the bottom. Its design principle is to use the contraction force of the spring to prevent air from entering the bottle to create a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward.

However, since the spring force and atmospheric pressure cannot give enough force, the piston cannot be attached to the bottle wall too tightly, otherwise the piston will not be able to rise and move forward due to excessive resistance; on the contrary, if the piston is to be easy to move forward and material leakage is likely to occur, Therefore, airless dispenser bottles have very high requirements on the professionalism of manufacturers, and not all manufacturers can produce airless pump bottles.

How we benefit from airless pump bottle

Cosmetic airless bottle prevents sensitive products (such as natural skin creams, serums, foundations and other paraben-free formulas) from being exposed to the air, thereby protecting their lifespan by up to 15 %. Also, through the physics of squeezing air, no residue is left inside the bottle. So is it worth having a airless pump bottle that can prevent bacteria from contacting the emulsion, preserve freshness and prolong the freshness of the product?
