For PVC, sayqat-Lu's fen, polyester, nylon, and so on film, because of their larger surface tension of the usual business card printing and membership card product requirements can be direct business card printing and membership card production (the actual requirements of the customers because in recent years, these materials in business card printing and membership card before or after a treatment), and is not handled by the polyolefin film surface tension is very low, such as pE is 31 Dyne, pp 29a Dyne, to business card printing and membership card-making should be increased to 38 Diane 2, this requires surface treatment on the film.

对于聚氯乙烯、赛璐玢、聚酯、尼龙等薄膜，因其表面张力较大，一般在制卡和会员卡制作产品要求不高时可直接制卡和会员卡制作（实际由于近年来客户要求的提高，这些材料在制卡和会员卡制作前也要经过处理），而未处理过的聚烯烃薄膜表面张力很低，如pE为31达因、pp为29达因，为了制卡和会员卡制作应将其提高到38达因2上，这就需要对薄膜进行表面处理。
