Premium Three Side Seal Film Sachet for Cosmetic Face Mask.
Custom flexible packaging for single sheet masks, constructed with 4-layer BOPET/AL/BOPET/IPE composite film.
Outer BOPET offers superb printability and scratch resistance. AL foil delivers high barrier against oxygen, moisture and light to retain serum activity. The intermediate BOPET protects aluminium foil from cracking. Inner IPE ensures stable heat sealing and cosmetic compatibility.
Three-side seal design provides consistent sealing strength to prevent leakage. Optional tear notch and custom gravure printing are available for cosmetic brands.
Product Features

Four-layer BOPET/AL/BOPET/IPE Composite Barrier Structure
The 4-layer laminated construction delivers outstanding comprehensive barrier performance. Outer BOPET provides excellent surface stiffness and printing adaptability. AL foil effectively blocks oxygen, moisture and ultraviolet light, suppressing oxidation and volatilization of mask serum. The middle BOPET layer protects aluminium foil against pinholes and cracking during converting and transit. The innermost IPE layer offers stable heat-sealing performance and good compatibility with cosmetic essence. It long-preserves the activity of mask serum and reduces the risk of product deterioration throughout shelf life.
Stable Three-side Sealed Construction
Precision three-side sealing process ensures uniform and consistent seal strength across the full edge. The sealed perimeter resists liquid permeation under stacking, extrusion and temperature fluctuation during warehousing and long-distance transportation, minimizing essence leakage risk. Flat and neat seal edge also improves the overall appearance of finished pouches.


Optional Pre-cut Tear Notch
Custom pre-cut tear notch can be added upon request. It enables clean, straight tearing without the need for scissors. The pouch maintains complete integrity before opening, preventing accidental leakage. It balances easy opening experience for end consumers and good seal security for bulk packaged goods.
Custom Gravure Printing Support
Supports high-definition gravure printing with rich colour reproduction and fine graphic restoration. Custom sizes, colour schemes and brand artwork are available to match brand visual positioning. The printed surface features scratch resistance, maintaining exquisite visual effect during circulation, helping cosmetic brands build differentiated packaging and boost product added value.
