Forms and technological process of winding film use Core tips: high transparency facilitates the identification of goods; high longitudinal elongation facilitates pre-stretching and saves material consumption; good puncture properties and transverse tear strength allow the film to encounter sharp corners or edges of goods without breaking at high stretching multipliers; high yield point makes the packaged goods tighter. One of the forms of winding film use is sealed packaging This type of packaging is similar to shrink wrap packaging, where the film is wrapped around the pallet to encase it all, and then two heat grippers heat seal the film together at both ends. This was the earliest form of wrap-around film used, and this led to the development of many more forms of packaging One of the forms of winding film use is full width packaging This type of packaging requires a film width wide enough to cover the pallet, the shape of the pallet is regular, so the use of it has its, suitable f […]
