Varmekrympemaskin: Innovator innen produktemballasjeindustrien

Den varmekrympemaskin pakker produktet inn med varmekrympbar film og varmer det opp for å forme det. Med sine doble muligheter for "forseglingsbeskyttelse" og "visuell forbedring", har det blitt et standard emballasjeutstyr i mat-, medisin-, elektronikk- og andre industrier. Dens kjerneteknologi er å bruke termoplastisiteten til polymermaterialer - når filmen varmes opp til 120-180 ℃, omorganiseres molekylkjeden fra en uordnet tilstand til en kompakt struktur, og krympingshastigheten kan nå 30% -70%, og passer dermed tett 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.
