It is modern it is deep in the world liked, a kind of rather popular and synthetic material for being also widely used.The global usage amount of PVC film exists
Second is in various synthetic materials.In the material that can produce three-dimensional table facial mask, PVC is most suitable material.PVC film
Production craft step generally include：Raw material → kneading → cold mixing and → extrusion-blown modling → PVC glass paper-based membrane → antistatic, heat
Seal coating processing → cutting → inspection → packaging → finished product.Inflation film manufacturing machine, blown film would generally be used in PVC film production process
Had higher requirements during machine blown film for blast, high-quality PVC film depends on constant blast.But existing blown film
Usually occur the too high phenomenon of blast in machine, therefore design a kind of relief valve pressure release is carried out when blast is too high and just seem to closing weight
Will.
