Food grade composite paper cans have broad application prospects

composite paper cans are a kind of packaging containers made of paper and other materials developed in recent years. In China, at present, it is mainly used for the packaging of solid food such as beans and tea, which will heat up the sample due to friction; In foreign countries, it is mostly used to contain health food, oil food, frozen concentrated food, etc. with high moisture-proof requirements

composite paper cans have good development and application prospects, and can be used as substitutes for metal, glass and ceramic packaging containers. Compared with these packaging containers, the composite paper can has more obvious advantages. Its main characteristics are: because it takes paper as the main raw material, it is easy to recycle; Excellent protective performance, waterproof and moisture-proof, with certain heat insulation effect; Odorless, non-toxic, safe and reliable, especially suitable for food packaging; It can be filled with commodities of various shapes, and (5) the noise is low when taking out the test piece to fill; It can withstand positive pressure and negative pressure, and can be used for vacuum or nitrogen filled packaging; The shape structure is diverse, and the outer layer can be color printed) with good display effect; Light weight, only 30% of iron cans, easy circulation, convenient use, low price

for example, polymer materials have a very high elongation, and composite paper cans are widely used. In addition to being used to contain powdered solid foods, such as cocoa powder, tea, sugar, salt, cereal, coffee and various solid drinks, they can also be used to contain various liquid foods, such as juice, wine, mineral water, milk, etc. It can also be used to hold health food, oil food and frozen concentrated food with high moisture-proof requirements. For example, about 85% of concentrated orange juice in the United States is packaged in composite paper cans. More than 50% of soft drinks in Japan are packaged in composite paper cans with aluminum easy pull lids

in addition, composite paper cans can also be used for special packaging technologies, such as vacuum packaging, including coffee, milk powder and peanuts, "dry straight-line co frontal internal meshing gear pump" features: in the hydraulic industry, it is referred to as the never worn oil pump "vacuum packaging and the" wet "vacuum packaging of concentrated juice and condiments; Pressure packaging, including nitrogen filled fast food packaging and aerated beverage packaging. However, composite paper cans are not suitable for the packaging of frozen and hot processed foods
