熱収縮機: 製品包装業界のイノベーター

の 熱収縮機 熱収縮フィルムで製品を包み、加熱して成形します。 「密封保護」と「外観向上」の2つの機能を備え、食品、医療、エレクトロニクスなどの業界で標準的な包装装置となっています。そのコア技術は、ポリマー材料の熱可塑性を利用することであり、フィルムを120〜180℃に加熱すると、分子鎖が無秩序な状態から緻密な構造に再配置され、収縮率が30%〜70%に達し、製品の輪郭にぴったりとフィットします。

の 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.
