Many of the products in today's era require different style of packaging that must be flexible and even attractive. Shrink wrap packaging is an ideal solution for packing uneven shape objects with flexibility and ease. Shrink wrap is a process under which the product to be packed is covered with a shrink film, which is then heated so that it shrinks on the product. The shrink film is a polymer plastic film made of PVC, polyethylene, polypropylene, or polyolefin. Mostly Polyolefin with different thickness, strength, clarities, and shrink ratios is used as a shrink film. The film is heated with the help of a handheld gun, or the product along with the film is passed through the heating tunnel on a conveyor. Shrink wrap packaging serves the purpose of keeping the product stable and clean, and also helps make it tamper resistant. Shrink wrap packaging is used as an overwrap on boxes, cartons, pallet loads, and beverage cans. It is also used as a primary covering in many food items such as meats, cheese, plants, and vegetables. There are various shrink wrap packaging systems available in the market, which are equipped with different technologies such as sleeve wrappers, side sealers, shrink tunnels, and L-sealers.
