Invista 3301 PET Copolymer Packaging Resin (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced
Material Notes:	Carboxyl end groups: <30 meg/kg. Diethylene glycol content: <1.8 wt%. Acetaldehyde content: <2.0 ppm. Fines 0.1% through 28 mesh as manufactured. Moisture content <0.1% as manufactured. Chip size <1.8±0.3mm avg. dia. flat side. Crystallinity >50%. 3301 PET is a copolymer packaging resin with a nominal intrinsic viscosity of 0.75 dl/g. 3301 series resins have excellent melt and crystallization properties, offering easy processibility in injection molding and stretch-blow molding, especially in water-grade applications. Packaging made from this resin has excellent clarity and is noted for its dimensional stability, which prevents shrinkage and expansion of the container. It conforms to FDA Regulation 177.1630 for food contact and is widely used for single-serve beverage bottles, small liquor bottles, and other custom containers. Containers made from PET are light weight, have excellent clarity, are recyclable, and are shatterproof. Information supplied by the manufacturer. The Invista PET product line has been acquired by Indorama.
