2–12 cm PP/PE/PET Aluminum Foil Easy-Peel Sealing Film for Cosmetic Packaging

Product Overview

Our PP/PE/PET aluminum foil easy-peel sealing film is designed for cosmetic packaging manufacturers, skincare brands, filling factories, and contract packers that require reliable container sealing with convenient consumer opening. Available in customized diameters and dimensions from 2 cm to 120 cm, the sealing film can be matched with different cosmetic jars, bottles, tubs, refill containers, sample cups, and large-format packaging.

The structure combines an aluminum foil barrier layer with a heat-sealing layer selected according to the container material, including PP, PE, or PET. After heat sealing, the film forms a secure bond around the container mouth while retaining controlled peelability. Consumers can open the package by pulling the integrated tab or lifting the edge of the seal without using tools.

This easy-peel aluminum foil sealing film helps protect creams, facial masks, lotions, gels, body-care products, and other cosmetic formulations from leakage, contamination, moisture, dust, and unwanted opening. Printing, embossing, pull-tab shape, sealing strength, thickness, color, and dimensions can be customized for different packaging projects.

Cause

Cosmetic products often contain active ingredients, oils, fragrances, water, emulsifiers, botanical extracts, and other sensitive components. Without an effective inner seal, the product may be exposed to several packaging risks during filling, transportation, storage, and retail display.

Common problems include:

• Cream or gel leaking around the cap during transportation
• Dust or foreign particles entering the container
• Moisture loss that changes product texture
• Fragrance or volatile ingredients escaping
• Product oxidation after prolonged storage
• Loose caps causing seal failure
• Consumers being unable to identify whether the package has been opened
• Difficult-to-remove seals creating a poor user experience
• Incorrect sealing layers failing to bond with PP, PE, or PET containers

A standard foil liner may provide protection, but excessive sealing strength can make the package difficult to open. On the other hand, insufficient sealing strength may cause lifting, leakage, or incomplete adhesion.

Cosmetic packaging therefore requires a sealing solution that balances barrier performance, sealing reliability, peelability, appearance, and compatibility with the container material.

Solution

Our easy-peel aluminum foil sealing film is developed to provide a clean and secure seal while allowing controlled removal by the end user.

The aluminum foil layer provides an effective barrier against external contamination, moisture exchange, light, and odor transfer. The bottom heat-sealing layer is selected according to the container material:

• PP sealing layer for polypropylene containers
• PE sealing layer for polyethylene containers
• PET-compatible sealing layer for PET containers

During the sealing process, heat and pressure activate the sealing layer and bond the film to the container rim. The sealing conditions can be adjusted to create the required peel strength. This helps the seal remain intact during transportation while still allowing consumers to remove it smoothly.

For cosmetic jars and wide-mouth containers, a pull tab can be added to improve opening convenience. The tab shape, position, and dimensions can be customized according to the jar design and filling-line requirements.

We also support customized printing for brand names, product information, opening instructions, batch identification, logos, and decorative patterns. Printed easy-peel seals can strengthen brand presentation while also functioning as an inner protective closure.

Specifications

Important: The correct sealing layer must be selected according to the exact container material and surface condition. Container samples are recommended before mass production.

Application

Skincare Cream Jars

The film can be heat sealed onto the mouth of facial cream, eye cream, night cream, moisturizer, and anti-aging cream jars. It helps reduce leakage and protects the product before the consumer opens the jar.

Facial Mask Containers

Clay masks, sleeping masks, wash-off masks, gel masks, and other semi-solid products can easily move during transportation. An easy-peel foil seal helps keep the product inside the container and prevents contact with the cap.

Cosmetic Refill Packaging

The film is suitable for refill cups, replacement cartridges, and inner cosmetic containers. A pull tab allows consumers to remove the sealing film before inserting or using the refill unit.

Lotion and Gel Packaging

Wide-mouth lotion jars, body gels, aloe gels, hair masks, styling creams, and body-care products can be sealed with a compatible PP, PE, or PET sealing layer.

Cosmetic Sample Containers

Small sample jars and trial-size cups require a precise seal because the container mouth is small and the packaging may be distributed individually. Customized die-cut foil seals can improve cleanliness and presentation.

Professional and Salon Products

Large cosmetic tubs used for salons, spas, beauty clinics, and professional skincare products may require larger sealing dimensions. Customized sealing films can be produced for wide-mouth containers and bulk packaging.

How It Works

The easy-peel sealing film is placed over the clean and flat mouth of the cosmetic container. A heat-sealing machine applies controlled heat, pressure, and dwell time.

The sealing layer softens and bonds to the container rim. After cooling, the film creates a continuous seal around the opening.

The aluminum foil helps provide barrier protection, while the polymer sealing layer creates adhesion to the PP, PE, or PET surface. By adjusting the sealing-layer formula and sealing conditions, the peel strength can be controlled.

When the consumer pulls the tab, the film separates from the container rim in a controlled manner. A properly selected film should provide:

• Secure sealing during handling and transportation
• Smooth peeling without excessive tearing
• Minimal sealing residue on the container rim
• A clean and convenient opening experience
• Clear indication that the package has been opened

How to Choose

1. Confirm the Container Material

PP, PE, and PET have different surface and heat-sealing characteristics. Please confirm whether the container is made from PP, HDPE, LDPE, PET, or another material.

2. Measure the Container Mouth

Provide the inner diameter, outer diameter, sealing-rim width, and required tab dimensions. The sealing film should cover the complete sealing surface without interfering with the cap.

3. Describe the Cosmetic Formula

Tell us whether the product is a cream, gel, clay mask, lotion, oil-based formulation, alcohol-containing product, or water-based formulation. Product ingredients may influence material selection.

4. Confirm the Required Peel Strength

A transport-heavy package may require stronger sealing, while a premium skincare jar may require a softer and smoother peel. Peel strength can be adjusted according to the project.

5. Provide Sealing Equipment Information

Please provide the sealing-machine type, temperature range, pressure, sealing time, and filling-line speed. These details help us recommend a suitable structure.

6. Choose the Surface Design

The seal can be supplied as plain aluminum foil, white foil, printed foil, embossed foil, or private-label packaging. Pull tabs and special shapes are also available.

7. Test Samples Before Mass Production

Because cosmetic containers may use different resins, additives, coatings, and rim designs, sample sealing tests are strongly recommended before confirming a bulk order.

FAQ
