CPP films are also produced from a combination of various grades of PP polymer. CPP films are usually cheaper as the fixed investment is much lower than a BOPP line as the latter is biaxially oriented as compared to mono orientation of CPP films. Various constructions of CPP are available (multi layer options) which are used to cater to several applications in general packaging, as a sealant layer in conjunction with other plastic substrates for packaging of food products, twist wrap usage in candies, etc. Key characteristics of CPP films are:



High Clarity and Gloss

Higher seal strength

Good hot tack strength

Good anchoring of inks and adhesive to Treated Surface

Good machinability on Packaging line

Resistance to grease and oil

Good resistance to tears & puncture

Good moisture barrier
