Heat Shrinking Machine: Innovator sa Product Packaging Industry

Ang makinang pampaliit ng init binabalot ang produkto gamit ang heat shrinkable film at pinapainit ito upang mahubog ito. Sa dalawahang kakayahan nito ng "proteksyon sa sealing" at "pagpapahusay ng visual", ito ay naging isang karaniwang kagamitan sa packaging sa pagkain, gamot, electronics at iba pang industriya. Ang pangunahing teknolohiya nito ay ang paggamit ng thermoplasticity ng mga polymer na materyales - kapag ang pelikula ay pinainit sa 120-180 ℃, ang molecular chain ay muling inaayos mula sa isang hindi maayos na estado patungo sa isang compact na istraktura, at ang rate ng pag-urong ay maaaring umabot sa 30% -70%, kaya malapit na umaangkop sa tabas ng produkto.

Ang 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.
