高溫真空袋和冷凍真空袋一樣，也是典型性的聚烯烴類高聚物。二種真空袋有很多共同之處，比如無臭、無氣味、環(huán)保等特性；耐酸性、堿、鹽及多種多樣化合物，特性平穩(wěn)；物理學及物理性能平衡；防潮性、防水性優(yōu)質(zhì)，有一定的阻氧性、耐磨性能；具備優(yōu)良的成形性和非常好的熱封合性。和高溫真空袋一樣，高溫真空袋也具備總產(chǎn)量大、來源于普遍、質(zhì)優(yōu)價廉的優(yōu)勢。
高溫真空袋和冷凍真空袋對比，主要的區(qū)別有以下幾個層面：
一、高溫真空袋的耐熱性遠好于冷凍真空袋，能夠耐120℃之上的高溫，高溫真空袋包裝食品類乃至可以承擔140℃之上的高溫蒸制的規(guī)定。
二、高溫真空袋的透光性和抗壓強度也好于冷凍真空袋。高溫真空袋的耐磨性能雖不是很理想化，但比冷凍真空袋好。
三、和冷凍真空袋類塑膠對比，高溫真空袋的關(guān)鍵缺陷是抗寒性差，高溫真空袋均聚物在0℃即很有可能主要表現(xiàn)出顯著的延性。
以上總結(jié)出來，高溫真空袋和冷凍真空袋差別還是十分大的，看商品的包裝規(guī)定來分辨哪些的真空袋適合，并不是較貴的便是是的，僅有看合不適合的才算是功能比較好的。
What is the difference between high temperature vacuum bag and freezing vacuum bag
High temperature vacuum bags, like refrigerated vacuum bags, are also typical polyolefin polymers. The two types of vacuum bags have many things in common, such as odorless, odorless, environmental protection and other characteristics; resistance to acid, alkali, salt and a variety of compounds, stable characteristics; balance of physics and physical properties; high moisture resistance and water resistance, It has certain oxygen barrier and wear resistance; it has excellent formability and very good heat sealability. Like high-temperature vacuum bags, high-temperature vacuum bags also have the advantages of large total output, universal origin, high quality and low price.
Compared with high temperature vacuum bags and refrigerated vacuum bags, the main differences are as follows:
1. The heat resistance of high-temperature vacuum bags is much better than that of refrigerated vacuum bags. It can withstａnd high temperatures above 120°C, and high-temperature vacuum bags can even meet the requirements for high-temperature steaming above 140°C.
2. The light transmittance and compressive strength of high-temperature vacuum bags are also better than those of frozen vacuum bags. Although the wear resistance of high-temperature vacuum bags is not ideal, it is better than that of refrigerated vacuum bags.
3. Compared with refrigerated vacuum bag plastics, the key defect of high temperature vacuum bags is poor cold resistance. High temperature vacuum bag homopolymers are likely to mainly show significant ductility at 0°C.
To sum up, the difference between high-temperature vacuum bags and refrigerated vacuum bags is still very large. You can see which vacuum bags are suitable according to the packaging regulations of the product. It is not the more expensive one that is the best. Only the ones that are suitable are not suitable. It has better functions.
