This 100μm white PET laminated heat-sealable, easy-peel lidding film is specifically designed for top-lid sealing applications. It serves as a preferred functional packaging material for the food, pharmaceutical, and daily chemical industries, offering four core advantages: strong sealing integrity, ease of opening, high barrier properties, and excellent processability.

I. Structure and Core Performance

Typical Structure: The outer layer consists of 100μm white BOPET (providing rigidity, light-blocking properties, thermal resistance, and printability), while the inner layer is a modified, easy-peel PE/EVA heat-seal layer; the two layers are bonded via dry lamination.

Key Performance Features:

Heat Sealability: Features a wide heat-sealing window (125–175°C), making it compatible with high-speed packaging lines; ensures stable seal strength and provides effective protection against liquid and gas leakage.

Easy-Peel Functionality: Peel strength is controlled within the range of 5–12 N/15mm, allowing for effortless manual opening; leaves no stringing or adhesive residue, creates a clean opening, and does not contaminate the container or its contents.

Barrier & Protection: The white PET layer offers superior light-blocking capabilities, acts as a barrier against oxygen and moisture, and demonstrates resistance to grease, acids, and alkalis, thereby extending product shelf life; it also possesses high mechanical strength, puncture resistance, tensile strength, and thermal stability.

Processability: Features a flat surface with excellent ink adhesion following corona treatment; exhibits tight thickness tolerance and low heat shrinkage, making it fully compatible with various processing techniques such as die-cutting, slitting, and printing.

II. Application Scenarios

Food Packaging: Ideal for sealing yogurt cups, jelly cups, sauce containers, pre-prepared meal trays, and ready-to-eat meal boxes, balancing the need for product freshness with convenient access.

Pharmaceuticals / Daily Chemicals: Suitable for sealing ointment tubes, health supplement bottles, cosmetic jars, and reagent bottles, meeting strict hygiene standards while ensuring easy access for users.

Industrial / Electronics: Used for sealing trays containing electronic components or precision parts, providing effective protection against dust and moisture while facilitating easy retrieval of contents.
