The most popular materials used for retort pouch include: PET / PE / CPP / VM PET / NY / Aluminum Foil.

Stand up pouch material structure

LDPE(Low-density polyethylene): is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic parts for computer components, and various molded laboratory equipment. Its most common use is in plastic bags.

HDPE (High-density polyethylene): is known for its high strength-to-density ratio. This plastic is usually milky white or semi-translucent, has superior puncture, low permeability and temperature resistance, and is more rigid and stronger than LDPE / LLDPE but also tears easier and has a propensity to crinkle.

PVDC: Polyvinylidine chloride, the excellent oxygen and moisture barrier properties of PVDC make it a ideal material for packaging converters. But the high cost of PVDC tends to mean that it is mainly used in the form of copolymers.

PET: Polyethylene terephthalate, is a very strong clear glossy film, and possesses a great number of advantages, such as good moisture and gas barrier properties, tensile strength, etc.

BOPP (Biaxially-oriented polypropylene): BOPP films are easy to produce with low costs. They have good chemical compatibility and offer superior moisture vapor barrier properties.

(Kraft) paper: has high tensile strength and elasticity, good tear resistance and is designed for packaging products with high demand for strength and durability. It is used for products like single multiwall paper bags and sacks (for cement, food, chemicals, consumer goods, flour bags etc.), sale bags for bakery products, wrapping.

Aluminum foil and metalized substrates: Aluminum foil has the best dead fold properties. It provides an excellent 100% barrier to all gases, moisture and light. It is a good reflector of radiant heat, usually supported with plastic and/or paper (in multy-layer structure) because it cracks when folded. Alone does not provide an acceptable aroma or odder barrier.

Metalized PET: are polymer films coated with a thin layer of metal, usually aluminium. They offer the glossy metallic appearance of an aluminium foil at a reduced weight and cost.

EVOH (Ethylene Vinyl Alcohol): is produced by a controlled hydrolysis of ethylene vinyl acetate copolymer. It’s most important characteristic is the outstanding Oxygen and odor barrier properties. Packaging structures with EVOH provide high retention of flavors, and prevent quality loss associated with reaction of oxygen with the product.

CPP (Cast Polypropylene): offer excellent heat seal strength, good thermal stability, good puncture resistance, good clarity and fair barrier properties. The film type also has good yield economics owing to its low density. Some of the typical application areas for the film includes hot filling and retort applications, high speed application on FFS machines and bakery products.

PLA (Polylactic acid): Polylactic acid is thermoplastic aliphatic polyester synthesized from renewable biomass, typically from fermented plant starch such as from corn , cassava , sugarcane or sugar beet pulp. In 2010, PLA had the second highest consumption volume of any bioplastic of the world. PLA is compostable, but non-biodegradable according to American and European standards because it does not biodegrade outside of artificial composting conditions.

PBS (Polybutylene succinate) : Polybutylene succinate is a thermoplastic polymer resin that has properties comparable to propylene. It is used in packaging films for food and cosmetics. In the agricultural field, PBS is used as a biodegradable mulching film PBS can be degraded by Amycolatopsis sp. HT-6 and Penicillium sp. strain 14-3. In addition, Microbispora rosea, Excellospora japonica and E. viridilutea have been shown to consume samples of emulsified PBS.
