背心袋的制作都有哪些材料?

  背心袋是许多商品使用的包装袋之一,通常大部分是一次性的,当商品从生产单位流通到消费者手中或到商品打开使用时,包装材料就完成了它的使命,作为废旧物资的回收或处置。因此,对于包装材料,一个是为了自己的更好的性能,以适应保护和促进商品的需要,第二是为了尽可能低的成本在今天的所谓的通用塑料,塑料如聚乙烯、聚丙烯、性能优良,大量材料印花背心袋,价格低廉等共同特点,可以选择材料是塑料包装材料;二是生产规模较大,性能较好,但较贵的通用工程塑料,如热塑性聚酯。至于昂贵的特种工程塑料增厚背心袋生产材料,虽然在某些性能上有独特的优势,但由于经济原因生产背心袋材料,一般不用于包装材料。
  Vest bag is one of the packaging bags used by many commodities, usually most of them are disposable. When commodities flow from the production unit to the hands of consumers or to the opening and use of commodities, the packaging materials complete its mission, as the recycling or disposal of waste materials. Therefore, for packaging materials, one is for better performance to meet the needs of protection and promotion of commodities. The second is for the purpose of keeping the cost as low as possible. In today's so-called general plastics, plastics such as polyethylene, polypropylene, excellent performance, a large number of materials with printed back center bags, low price and other common characteristics, plastic packaging materials can be selected. The second is the large-scale production and sex Can be better, but more expensive general engineering plastics, such as thermoplastic polyester. As for the expensive special engineering plastic thickened vest bag production materials, although it has unique advantages in some properties, but due to economic reasons, it is specialized in the production of vest bag materials, which are generally not used for packaging materials.
  背心袋的打印也可以说是核心,不管袋的材料有多好,如果毁在打印机里,一切都是徒劳。印刷质量受油墨、稀释剂、版面、打印机技术等因素影响,需要厂家严格控制。

  The printing of vest bag can also be said to be the core. No matter how good the bag material is, if it is destroyed in the printer, everything will be in vain. Printing quality is affected by printing ink, diluent, layout, printer technology and other factors, which need to be strictly controlled by the manufacturer.
  封切实际结合的过程中,切割,将印刷塑料薄膜焊接和切割,形成三个或双方背心袋的密封的部分材料,然后通过打孔机定型(如背心袋、扣袋风格)。密封和切割机的操作方法非常简单:电动的塑料薄膜放在两排金属热封板在塑料薄膜的方向,水平放置,一行一行垂直放置,然后分别从两个方向进行密封工作。其密封原理是,通电加热产生金属温度,当温度达到塑料薄膜的热温度时,可以让塑料薄膜的边缘粘合。而热粘接方法对塑料薄膜也有要求,材料必须具有较好的耐热密封性能,熔点较低。
  In the process of actual combination of sealing and cutting, cutting, welding and cutting the printed plastic film to form the sealed part materials of three or two vest bags, and then finalizing the design by punching machine (such as vest bag, buckle bag style). The operation method of the sealing and cutting machine is very simple: the electric plastic film is placed on two rows of metal heat sealing plates in the direction of the plastic film, horizontally, one row and one row vertically, and then the sealing work is carried out from two directions respectively. The sealing principle is that the metal temperature is generated by electric heating. When the temperature reaches the thermal temperature of the plastic film, the edge of the plastic film can be bonded. The hot bonding method also has requirements for the plastic film. The material must have good heat-resistant sealing performance and low melting point.
