PP PS PET Multi-layer co-extrusion Sheet Production Line
Product Details
The core of the line is our advanced multi-layer co-extrusion system, which can produce up to 5 layers of sheet. Each layer is carefully designed to optimize its barrier properties (oxygen, moisture), mechanical strength and thermal stability. Smart extruders and modular die designs enable seamless material combinations and customized layer thickness and arrangement. Whether producing lightweight rigid sheets for packaging or heat-resistant PET layers for industrial use, our technology ensures uniformity and consistency in each production batch.
>> PP, EVA, EVOH, PS, PE multi-layer co-extrusion barrier sheet production line
In order to meet the increasingly demanding requirements of users for products, we have independently developed double-layer three-layer and multi-layer asymmetric distribution technology, so that the products produced by this equipment can obtain better barrier properties.
>> PP, EVA, EVOH, EVA, PP five or seven layer co-extrusion composite high barrier fresh-keeping packaging sheet
It has excellent gas barrier properties, moisture resistance, and is a plastic packaging material with the best gas barrier properties. Mainly used in jelly packaging, high-end meat, fast food rice and other food packaging, medicine, cosmetics and other packaging.
Energy-saving and high-efficiency, high-speed output
Designed for sustainability and productivity, the line is equipped with an energy-saving extruder and an optimized screw design to minimize power consumption while maximizing output. The high-torque drive system and precision temperature control module ensure rapid melting and homogenization of raw materials, with production speeds up to 1,200 kg/h. Automatic thickness adjustment and real-time monitoring systems further reduce material waste, lower operating costs, and support environmentally friendly production practices.

Applications: Cross-industry versatility
From food-grade PP/PE barrier sheets for vacuum packaging to high-clarity PET sheets for medical blister packaging, the line is suitable for countless applications. Its ability to combine recycled materials with virgin polymers also supports circular economy initiatives. Industries such as automotive (interior panels), construction (insulation panels) and consumer goods (disposable tableware) benefit from the flexibility and output quality of this line.
