Cast polypropylene film is a polypropylene film produced by casting process, which can be divided into ordinary CPP and cooking CPP. It has excellent transparency, uniform thickness and uniform performance in vertical and horizontal directions. It is generally used as the inner material of composite film. The thickness of ordinary CPP film is generally 25 50 μ M. after compounding with OPP, it has good transparency, bright surface and strong hand feeling. This material is used in general gift bags. The film also has good heat sealing property. The thickness of cooking grade CPP film is generally 60 80 μ M, it can withstand high-temperature cooking at 121 degree for 30 minutes, has good oil resistance and air tightness, and has high heat sealing strength. Generally, the inner layer of meat packaging adopts cooking grade CPP film.
Fim CPP gen karakteristik sa yo nan transparans bon, segondè enteprete, bon rèd, bon rezistans imidite, rezistans chalè ekselan ak sele chalè fasil, ak rezistans enklizyon li yo ak aplikasyon pou machin anbalaj yo pi bon pase fim polyethylene. Se poutèt sa, fim CPP okipe yon pozisyon sèten nan jaden an nan fim anbalaj. Apre enprime ak fè sak, fim CPP yo itilize pou anbalaj manje, papye, makèt ak tekstil, li kapab tou itilize apre konpoze ak lòt fim mens. Li se jeneralman itilize kòm materyèl la kouch enteryè ak ekstèn nan fim konpoze. Li aplike nan anbalaj la nan divès kalite manje, ki gen ladan manje ki bezwen chofe ak esterilize, kondiman, soup ak nesesite chak jou.
Non angle PP plastik (polypropylène): Polypropylène espesifik gravite: 0.9-0.91g/cm3
Kontraksyon bòdi: 1.0-2.5 pousan
Fòme tanperati: 160-220 degre
Pwopriyete materyèl yo: ba dansite, fòs, rèd, dite ak rezistans chalè pi bon pase ba -polyethylene presyon. Li ka vin frajil nan tanperati ki ba, pa rezistan nan mwazi ak fasil aje Li apwopriye pou fè pati mekanik jeneral, pati ki reziste korozyon - ak pati nan apeprè 100 degre Li gen bon pèfòmans elektrik ak segondè {{3} } izolasyon frekans, ki pa afekte pa imidite, men pati pyès sa yo kwen.
