Blister packs have improved

Since the heat sealability of the bleached paperboard has been greatly improved, the use as a blister packaging material has also been better promoted. Everest heat-sealed packaging from International Paper and Printkote Easy Seal Plus from Midwest Weike used polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), PETG, and Aclar and other materials extrude cardboard coated materials on paperboard. All of these products have better low temperature sealing properties and shorter bonding time advantages than previously used materials, so the filling rate is increased and the risk of loss of contents and printed patterns due to overheating is reduced.
