The correct selection of packaging materials is an important condition for the effective application of inflatable packaging. Inflatable packaging must use materials with good air and moisture resistance properties to maintain the optimal gas composition inside the packaging. Plastics and their composites are widely used in inflatable packaging in the form of flexible packaging, Thermoforming platters and other forms due to their advantages of wide source, easy processing, portability and beauty. This mainly discusses the selection of plastic materials.
Commonly used materials with good gas and moisture resistance properties include PVDC, KOPP, PET, PET/PE, PT/PE, PA/PE, PP/PVDC/PE, PA/EVA/PE, PET/EVAL/PE, etc.
When selecting materials, the product characteristics and inflatable packaging requirements should be taken into account, as well as the source and price. For example, fresh meat can be packaged in inflatable packaging (65% -80% O2, 35% -20% CO2, refrigerated at 5 ℃), with materials such as PVDC, PET, PA, EVOH, etc; Choose inflatable packaging for pies (65% -80% O2, 35% -20% CO2, 30% N2), with materials such as PET/PE, PET/EVAL/PE, etc. available; Choose inflatable packaging for cauliflower (5% O2, 5% CO2, refrigerated below 10 ℃).
Inflatable packaging is commonly made of double-layer composite film or three-layer aluminum thin composite film with three sides sealed packaging bags. The thickness of the composite film is generally between 60-96 um, with the inner layer being a heat sealing layer that needs to have good heat sealing performance, with a thickness of 50-80 um. The outer layer is a sealing layer that needs to have good airtightness and printability, a certain strength, and a thickness of 10-16 um. Polyethylene (PE) is commonly used as the inner substrate of composite films, such as high-temperature resistant polypropylene (CPP) for high-temperature cooking bags, and stretched polypropylene (OPP), polyester (PET), nylon (PA), etc. are commonly used as the outer substrate. Some foods such as tea, milk powder, and some high fat foods require light blocking packaging to prevent the color, aroma, and taste of the food from being affected by light. The method is to composite a thin layer of aluminum foil (AL) between the inner and outer layers of the substrate, which also enhances its airtightness.
