高阻隔共挤膜

产品特点
Product characteristics

该产品是由我公司自行研制的，拥有多项专利技术。产品采用国外进口原料，以高阻隔树脂为中间层，通过多层共挤吹膜生产线生产而成。该产品具有优异的阻隔性、良好的热封性以及抗穿刺等机械性能。阻隔性能要好于肠衣膜十倍以上，可广泛应用于需要采用抽真空、充惰性气体进行保护的产品。
This product is self-developed by our company and has multiple patented technologies. The product adopts imported raw materials from abroad, with high barrier resin as the intermediate layer, and is produced through a multi-layer co extrusion blown film production line. This product has excellent barrier properties, good heat sealing properties, and mechanical properties such as puncture resistance. The barrier performance is better than that of the casing film by more than ten times, and can be widely used in products that require vacuum pumping and inert gas filling for protection.

性能

Product performance
1、高阻隔：能达到对氧气、水、二氧化碳、气味等高阻隔的效果。
High barrier, can achieve the effect of oxygen, water, carbon dioxide, odor and other high barrier

2、功能强：耐油、耐潮湿、耐120摄氏度的高温蒸煮，耐低温冷冻、保质、保鲜、保气味，可用于真空包装、无菌包装、充气包装。
Strong function, oil resistance, moisture resistance, 120 degrees Celsius high temperature cooking resistance, low temperature freezing resistance, quality preservation, fresh preservation, odor protection, can be used for vacuum packaging, aseptic packaging, inflatable packaging.
3、成本低：相对玻璃包装、铝箔包装及其他塑料包装，要达到的同样的阻隔效果，共挤薄膜在成本上具有较大的优势。由于工艺简单，所生产的薄膜产品成本与干式复合薄膜和其他复合薄膜相比可以减少10-20%。
Low cost, compared with glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, co-extrusion film has a greater advantage in cost.Because of the simple process, the product cost of the film can be reduced by 10% ~ 20% compared with dry composite film and other composite films

4、结构设计灵活：采用不同的结构设计，可以达到不同的保质需求。
Flexible structure design, using different structure design, can achieve different quality requirements

5、强度高：共挤薄膜在加工过程中具有拉伸的特点，塑料拉伸后可相应提高强度，也可以在中间加入尼龙、茂金属聚乙烯等塑料材料，使其具备超过一般塑料包装的复合强度，不存在分层剥离现象，柔软性好，热封性能优良。
High strength: The co extruded film has the characteristic of stretching during the processing. After plastic stretching, the strength can be correspondingly increased, and plastic materials such as nylon and metallocene polyethylene can be added in the middle to make it have a composite strength that exceeds that of ordinary plastic packaging, without delamination and peeling, with good softness and excellent heat sealing performance.

6、容量比小：可以采用真空收缩包装，这是玻璃、铁罐、纸包装所无法比拟的。
Capacity ratio is small, can use vacuum shrink packaging which is glass, tin, paper packaging can not compare.
7、透明度好，柔软性好，与产品贴合紧密
Good transparency, good softness, close fit with the product.
