Varmekrympende maskine: Innovator i produktemballageindustrien

Den varmekrympemaskine omslutter produktet med varmekrympende film og opvarmer det for at forme det. Med sine dobbelte muligheder for "forseglingsbeskyttelse" og "visuel forbedring" er det blevet et standard emballageudstyr i fødevare-, medicin-, elektronik- og andre industrier. Dens kerneteknologi er at bruge termoplasticiteten af ​​polymermaterialer - når filmen opvarmes til 120-180 ℃, omarrangeres molekylkæden fra en uordnet tilstand til en kompakt struktur, og krympningshastigheden kan nå op på 30% -70% og passer således tæt til produktkonturen.

Den working principle of the heat shrinking machine is based on the thermal responsiveness of material science. Taking PE film as an example, the memory effect formed by its biaxial stretching process can shrink and form in a short time under the infrared radiation of a quartz tube or stainless steel heater, and perfectly fit the special-shaped surface. The sealing layer formed after shrinkage can block the penetration of water and oxygen, extending the shelf life of the drug by 20%; for fragile products such as glass bottles, its cushioning performance can withstand a 1.5m drop impact. Compared with traditional carton packaging, the cost of PE film is reduced by 40%, and the automated production line reduces labor input by 60%. If wrinkles appear after shrinkage, check the uniformity of hot air circulation or adjust the conveyor belt speed.
