Plastic bag has been invented to meet that demand as fantastic solution. So how plastic bags are made?
Plastic may come as a by-product of oil refining, and uses only 4% within the total world's oil development. It is a 'biogeochemical' manipulation of certain properties of oil, into polymers, that behave 'plastically.' Plastic polymers are built into 5 main types, of which, plastic bags are made of the type known as Polyethylene. At it case, sometimes manufacturers will add an additive called impact modifier to make bags firm. When customers require plastic bags become be destroyed easily in lands, suppliers must mix biodegradable additives as EPI or DW2 with quantity 1 or 2% when extruding.
The 1st process is blowing film or called extruding membrane. All the materials always be put into extruding machine to make big plastic film function. In this steps, workers or technicians must control the bag rolls into smooth visual aspect.
The second step is printing process as well as mainly raised for shopping bags which most companies could change the printing image with their logo, brand name, information about products.When getting orders with printing image, manufactures creates printing plates (printing cylinders) to dedicate to printing technological machines. Images are analyzed into different colors; each colour will be controlled by one worker if the luggage need print many colors or printing images are difficult.
