为什么选择我们的复合卷膜?
Design validation and CAD digital model
高阻隔防护: 优异的隔氧与隔水性能,配合脱氧剂使用效果更佳,有效防止油脂氧化及霉变。
高速包装适配: The smoothness of the membrane surface is precisely regulated, with a constant coefficient of friction (COF) in the全自动枕式包装机上高速运转不跑偏、不卡机。
精美画质呈现: Adopting e-axis gravure color printing technology, high color saturation. Transparent window design (PET material) makes marbling and flow texture clearly visible.
严密封合性能: Modification of the PE inner layer ensures that it will remain in place under high speed sealing.封口严密、不漏气,显著降低返工率。

PET/PE laminated film - the "all-rounder" of packaging
PET is usually used as a laminating film外层(印刷层)。它耐高温、印刷性能极佳,且硬度高。
PE is usually used as a laminating film内层(热封层)。它柔韧性好,具有极佳的热封合性能。
This is the most common double-layer composite structure, combining the aesthetic stiffness of PET with the tough sealing of PE.
