Wrapping packaging refers to wrapping various products with regular or irregular shapes into a whole, so that the goods can be protected from scratches, bruises, no damage, no loss, and reduce economic losses caused by poor packaging. With the development of our country's economy, domestic and foreign enterprises have also continuously improved their packaging requirements.
Machine Stretch Film does not need to be heat-shrinked during the packaging process, which is beneficial to save energy, reduce packaging costs, facilitate container transportation, and improve logistics efficiency. The "collective loading and unloading" method combining pallets and forklifts reduces transportation costs, and the high transparency also facilitates identification of packaged items and reduces delivery errors. Stretch Film uses the super winding force and retractability of the film to bundle the product compactly and fixedly into a unit. Even in an unfavorable environment, the product does not have any looseness and separation, and there are no sharp edges and stickiness, so as not to cause damage. damage. At present, there are mainly two ways in wrapping packaging: manual wrapping wrapping and machine wrapping wrapping (automatic wrapping machine).
Machine stretch wrap adopts mechanical packing method when working, mainly relying on the movement of the goods to drive the die rolls for packing. The requirements for the tensile strength of the film are relatively high, and there are also certain requirements for the stretch rate of the film. The general stretch rate requirement is 300%, roll weight is 15KG. There are blue, red, yellow, green, and black, which are used by manufacturers to pack goods while distinguishing products, which is convenient for identifying goods.
