Do you know the classification of heat shrinkable films?

There are currently many classification methods for heat shrinkable films. Now the more commonly used classification methods are introduced as follows:Classification according to different types of plasticsSuch as common polyfeene heat shrinkable film, polyvinyl chloride heat shrinkable film, polyolefin heat shrinkable film, polystyrene heat shrinkable film, polyester heat shrinkable film, etc.Classification by film structureSuch as single-layer heat shrinkable film, multi-layer heat shrinkable film (also often specify the layer structure, such as containingEVOHfive-layer co-extruded heat-shrinkable film).Categorized by shrinkageFor example, bidirectional shrinkage film (the shrinkage rate of the film shrinking into the longitudinal direction is equivalent to the shrinkage rate in the transverse direction) and unidirectional shrinkage film (the shrinkage rate of the film shrinking into the transverse direction is significantly greater than that in the longitudinal direction, or the shrinkage rate in the longitudinal direction is significantly greater than that in the transverse direction). shrinkage); high shrinkage shrink film (shrinkage in50%above) and low shrink shrink films (shrinkage at20%left and right) and so on.More flexible packaging bag expertise http://www.yltpacking.comIf you have customized packaging bag requirements
