Polyester sheet series, including PETG, APET and PCT, is a new sheet product developed and developed rapidly in recent years. Polyester sheet has many advantages, such as excellent comprehensive performance, high transparency, good strength and easy post-processing. Because of its good strength and the same thickness of products, its protective effect is obviously better than that of PVC sheet. If the same strength is compared, thinner polyester sheet can be used.

Therefore, although the weight and price of polyester sheet are higher, the actual cost is not increased much.
What’s more, the transparent crystal of polyester sheet increases the packaging effect and makes the packaging a higher grade. In addition, it is non-toxic, odorless, tasteless, in line with the hygienic requirements of food packaging, it does not have the problem of secondary environmental pollution when PVC sheet is burned.

In the case that PVC sheet is prohibited to be used in disposable packaging, the sheet with higher strength that can meet the packaging application is undoubtedly polyester sheet. The processing of polyester sheet (blister or folding box) is convenient, and the ordinary blister machine can process normally, and the efficiency is the same as that of PVC sheet.
Therefore, the original equipment for producing PVC sheet Blister products does not need any modification.
