Industrial Laminated Heat Sealing Film

The Industrial Laminated Heat Sealing Film produced by Jincheng suppliers has a standardized thickness range of 15μm, 25μm, 30μm, and 40μm. It covers everything from thin composite liners to heavy-duty industrial packaging, meeting the needs of various industrial composite production scenarios.

This product adopts a modified industrial-specific heat sealing formula. The heat sealing temperature range is wide and stable. The edge sealing is dense and uniform, and it is not easy to peel off or crack after forming. It is suitable for continuous operation of fully automatic or semi-automatic composite sealing production lines. It is equipped with dual-sided differentiated precise corona treatment. The inner side has a 52-54 dynes coefficient to ensure the adhesion of multi-layer composite, printing, and gluing. The outer side has a 42-46 dynes coefficient for smoothness and anti-adhesion. The material runs smoothly without deviation when being processed.

The transparent model is suitable for general industrial composites and food sealing. The aluminized model relies on a high-barrier metal coating to achieve multiple protections against moisture, light, and oxidation. It is widely applicable to industrial composite substrates, food lock-sealing packaging, and daily chemical and pharmaceutical sealing packaging.

Real user purchase reviews

【Industrial Composite Processing Factory | Batch Repeat Purchasing Customers】

We have been purchasing Jin Cheng Industrial Laminated Heat Sealing Film for multi-layer composite substrate production for a long time. After comparing with products from multiple factories, the biggest advantage of this product is its extremely strong parameter stability. The whole roll is uniform in thickness, the temperature range for heat sealing has a wide tolerance, and the workshop equipment does not need to frequently adjust parameters. Continuous composite production has almost no layering or edge cracking issues. The corona value is stable, the composite adhesion meets the standards, the batch production loss rate is significantly reduced, and it is suitable for long-term large-scale industrial mass production. The supply is stable, the batch consistency is high, and it is our fixed industrial film supplier.

【Food Packaging Enterprise | Beverage, Meal Box Sealing Customers】
