Multi layer co extrusion high barrier film production line

Multi layer co extrusion high barrier film production line

Plastic film has a certain shielding ability against small molecule gases, liquids, and odor molecules. The permeability coefficient is usually used to indicate the size of plastic's impermeability.

Currently, commonly used high barrier packaging materials include PVDC, EVOH, and PA.

1、 Introduction to PA high barrier film and production equipment

1. PA high barrier film has good barrier properties, with better barrier properties than PVDC sheet at high temperatures, but lower barrier properties than PVDC sheet at room temperature. With our PA sheet production machine, we can produce PA three-layer sheets, PA five layer sheets, and PA seven layer sheets. The raw materials used are usually PA, PS, PP, PVC, PE, and HIPS. Usually used for general food packaging.

2. Jinweier PA high barrier sheet production line

Our PV high barrier sheet production line adopts multi extruder co extrusion technology to produce multi-layer co extruded composite PA high barrier sheets, such as ABA, ABCBA, ABCDCBA and other multi-layer structures, which are widely used in thermoforming, general food packaging, etc.

*Our PA high barrier sheet production line is equipped with precision multi-layer distributors, with uniform layering, adjustable layer ratios, and precise digital control

*The equipment is equipped with specially designed screws and barrels, which have good plasticizing ability and are combined with advanced production processes to effectively eliminate defects such as crystal removal points, white spots, and black spots

*The inclined horizontal tablet structure makes operation and maintenance more convenient

*Roller independent power, synchronous closed-loop control of linear speed and extruder speed

*Jinweier independently developed an electronic control operating system. Touch screen operation, PLC control, high degree of automation, saving material and labor costs;

Our PA high barrier sheet production equipment has a compact structure and superior performance. The screw and barrel have been optimized for design, and the whole machine has the advantages of good plasticizing ability, stable extrusion, high output, and long service life.

2、 Introduction to PVDC High Barrier Film and Production Equipment

1. PVDC high barrier sheet has high barrier properties and chemical resistance. Using our PVDC sheet production machine, we can produce PVDC three-layer sheets, PVDC five layer sheets, or PVDC seven layer sheets. The raw materials used are usually PVDC, PS, PP, PVC, PE, and HIPS. Usually used for packaging yogurt, jam and other foods, it has good preservation function.

3、 Introduction to EVOH High Barrier Film and Production Equipment

The barrier effect of EVOH high barrier sheet is more than ten times higher than that of PVDC high barrier sheet. Our EVOH sheet production machine can produce EVOH three-layer sheets, PVDC five layer sheets, or PVDC seven layer sheets. The raw materials used are usually EVOH, PS, PP, PVC, PE, and HIPS. Usually used for food packaging such as dairy products, meat, and canned goods, as well as packaging for chemicals, electronic components, and pharmaceuticals.
