Quietly tell you frozen food packaging common problems and solutions ( A)

Due to the situation, all the food are selling very fast, including frozen food. This not, small make up to see we have a customer message website encountered the problem of frozen food bags. Today we're going to analyse the: problem a: compressive strength; Under low temperature environment performance of packaging materials, packaging is very easy to become fragile, cause detonation bag. Countermeasures: for goods under different temperature, the application without the same material supplement, such as goods in - Even - 18 ℃ 30 ℃ low temperature cold storage in the natural environment, strongly recommended material supplement: NY/PE, PET/NY/LLDPE, PET/NY/AL/PE, NY, Polyester) The material performance in low temperature environment is relatively stable, with low temperature resistance, impact resistance, prevent the features, such as centesis can be prevented in the whole process of transport and storage because of its impact and explosive bag. Problem two: easy tear problem; Frozen food packaging bags for customers to use when play is easy to tear the mouth is convenient, but in the whole process of transport and storage is inevitable to produce impact, causing the easy tear mouth open, make the cold storage bags lost its efficacy. Countermeasures: adjust the shape of easy tear mouth, basic easy tear mouth is chosen as shown in figure 1. 0 shape, but the material performance under low temperature environment, easy tear force may narrow mouth, and we can use this not easy tear in the shape of mouth. Can be used as shown in figure 1. 1 easy tear in the shape of mouth, through the observation will find, easy to tear the mouth is a circular arc shape, according to the basic principle of structural mechanics, arc shape of force are easy to tear, and even material performance, also can't literally torn off. There are two problems and everybody said, frozen food bags sealing and produce the problem of the fog, said too much afraid we can't digest, next article continue with all of you.
