Plastic bags manufacturing Cape Town
: Packaging has been the need of human kind from early time for storing, transporting and preserving foods, goods and other products. With the dramatic innovation of technology, the interaction between people from different areas, different countries increase and demand of trading rises day by day, packaging in a most convenience way is necessary and vital. Thus Plastic bag manufacturing becomes imperative as an excellent solution to meet that demand.
Plastic comes as a by-product of oil refining, and uses only about 4% of the total world’s oil production. It is a ‘biogeochemical’ manipulation of certain properties of oil, into polymers, that behave ‘plastically.’ Plastic polymers are manufactured into 5 main types, of which, plastic bags are made of the type known as Polyethylene. From polyethylene, resins are produced and come straight into production of plastic bags.
With special types needed for different purposes such as food plastic bags, butcher’s bag, shopper plastic bags, luxurious plastic bags etc. manufacturers like CT packaging, 100% virgin resins are used to make the best quality plastic bags: strong, smooth and with nice appearance. Customers who also require other film colors of plastic bags for impressive looks are also provided with their choice. Manufacturers add master batches (color resins) to change from transparent to different colors. In some case, manufacturers add an additive called impact modifier to make bags strong. When customers require plastic bags which can be destroyed easily in lands, biodegradable additives such as EPI or DW2 are added to the resins with when extruding.
Plastic manufacturing include blowing film or extruding film. Here, all the materials is sent to an extruding machine to make big plastic film roll. During this stage, workers must ensure the bag rolls into smooth appearance.
The second step is printing process which is mainly used for plastic shopping bags which many companies could customize the printing image with their logo, brand name, information about products etc. When getting orders with printing image, manufacturers will create printing plates (printing cylinders) to put into printing machines. Images are analyzed into different colors which are then brilliantly printed on the plastic bag.
The third step is cutting and sealing process. The plastic rolls are cut into different shapes and handles based on customer preference and purpose. There are a lot of cutting machines available for different purposes: soft loop, patch handle, rigid, flat merchandise, etc
For special ones such as drawstring plastic handle bags, rigid plastic handle bags, soft loop plastic handle bags, they usually require some manual steps which cannot be implemented by automatic machine. In manual workshop, workers have to sew the handles into the bags, putting the cardboard into gussets (customized according to customer’s requirement), punching the hole etc.
