五金用品包装膜

一、五金用品包装膜材质

五金用品包装膜是什么材质？ 本品优选双向拉伸聚丙烯薄膜（BOPP）为基材，并融合特定增韧配方。BOPP材质本身具备优异的物理稳定性与光洁度，经合理改性后，其柔韧性与抗穿刺性能显著提升，能紧密贴合螺丝、轴承等异形五金件，提供持久稳固的保护。

二、 五金用品包装膜核心特点

1.五金用品包装膜具有较高透明度

BOPP材质赋予五金用品包装膜面卓越的光学性能，透光率可达90%以上。包装后能高清呈现五金件的原色与光泽，无需拆封即可精准辨识产品型号与表面工艺，兼具防护与展示功能。

三、 五金用品包装膜使用方式

1. 手工包裹

裁切适当长度的膜，直接缠绕或包裹五金件，利用膜自身的静电吸附力或轻微加热收紧，使其服帖覆盖。

2. 机器封装

适用于L型封口机或枕式包装机，设定适宜温度（通常建议130℃-160℃），膜受热收缩后即可紧密贴合产品外形，形成规整美观的包装效果。

A, hardware packaging film material

What is the material of hardware packaging film? Biaxially oriented polypropylene (BOPP) is selected as the base material, and a specific toughening formula is blended. BOPP material itself has excellent physical stability and smoothness. After reasonable modification, its flexibility and puncture resistance are significantly improved, and it can closely fit special-shaped hardware such as screws and bearings, providing lasting and stable protection.

Second, the core characteristics of hardware packaging film
1. The packaging film of hardware products has high transparency.

BOPP material endows the packaging film surface of hardware products with excellent optical properties, and the light transmittance can reach over 90%. After packaging, the original colors and luster of the hardware can be displayed in high definition, and the product model and surface technology can be accurately identified without unpacking, which has both protection and display functions.

Three, the use of hardware packaging film
1. Handmade parcels

Cut the film with appropriate length, directly wrap or wrap the hardware, and tighten it by using the electrostatic adsorption force of the film itself or slight heating, so that it can be covered.

2. Machine packaging

It is suitable for L-type sealing machine or pillow packaging machine. When the appropriate temperature is set (usually 130℃-160℃), the film can closely fit the product shape after being heated and shrunk, forming a regular and beautiful packaging effect.
