Coated PVDC barrier packaging film

The method through the co-extrusion composite equipment (co-extrusion blow moulding or co-extrusion casting equipment) will be pressure-sensitive adhesive layer and the substrate layer synchronous extrusion, composite, surface protection film, this method is the application of co-extruded production

Firstly, let's understand what is a coating machine?Coating machine is mainly used for film, paper and other surface coating process production, this machine is the rolls of substrates coated with a layer of specific functions of the glue, paint or ink, etc., and drying and winding.The use of specia

I. Production of polythene heat-shrinkable filmThe production of polyethylene heat-shrinkable film for packaging can be carried out either by the single-bubble method (direct blow-moulding, with only one blister) or by the double-bubble method (firstly making a blank film, which is then heated an

Various processing techniques have been developed to produce unidirectional and bi-directional stretch PET films. Typical processing includes the following steps:① Extrusion of PET using a hanger type die.② Quenching stage;③Deformation stage;④ Post-processing stage.At the beginning of the process, t
