Why use composite packaging? Qitech Packaging, a specialist flexible packaging manufacturer, believes that improving the properties of existing plastic materials, increasing the strength and barrier properties of materials, developing new types of materials, reducing the amount of materials used (thick walls), reusing materials, and sorting and recycling materials to protect the environment are the reasons for using composite packaging bags.
New high - barrier plastics have been widely used
The new type of high barrier plastic can not only enhance the protection function of the packaging for food, but also reduce the amount of plastic, and even realize the reuse of materials. For the processing food that requires the use of high barrier protection packaging, as well as the application of vacuum packaging, inflatable packaging and other packaging occasions, we generally have to use composite packaging, and in the multilayer composite material must use more than one layer of high barrier material.
Commonly used high barrier packaging materials include aluminum foil, nylon, polyester and so on. With the improvement of food packaging protection requirements, ethylene - vinyl alcohol copolymer, polyvinyl alcohol and other materials with better barrier properties have been gradually widely used. At present, PEN(polyethylene naphthalene diformate) has been developed and applied in a small amount in developed countries, which has added many advantages for food packaging materials. The chemical structure of PEN is similar to that of PET, but its rigidity is greatly improved, and its oxygen and water resistance are also several times higher than that of PET. Besides, PEN has good ultraviolet absorption and lower gas adsorption. In this way, the container containing food with PEN material does not smell and can be reused.
Inorganic high barrier microwave food packaging materials will become a new favorite
With the rapid pace of consumer life, food packaging which can be directly used for microwave heating will become a new hot spot in the field of food packaging development. Due to the current use of aluminum foil and some plastic composite materials made of packaging has opaque, not easy to recycle, can not be directly used for microwave processing and other shortcomings, in recent years, the newly available Siox-plated materials can be used as a good substitute. SiOx material is a kind of thin layer silicon oxide coated on PET, PA, PP and other substrates. It not only has better barrier performance, but also has excellent adaptability to atmospheric environment. The barrier property of SiOx material is hardly affected by the change of ambient humidity and temperature. SiOx coating has high barrier, high microwave transmittance, transparency, can be used for microwave processing food soft packaging, can also be made into beverage and edible oil packaging containers. SiOx material has also been applied in China. Although the cost of SiOx coating is high and the large-scale commercial production technology is not perfect, because of its special properties, SiOx coating will become an important packaging material in this century.
