各类不同面料材质拉链袋生产要点

①BOPP或哑光膜类拉链袋

① BOPP or matte film zipper bags

印刷工序：需要使用耐温性油墨，而不能用普通轻包油墨，版面设计尽量设计为边封留2mm以上的透明边为佳，如果整版设计图案的，尽量设计为有托白设计（即色墨下面有白色油墨层）。

Printing process: It is necessary to use temperature resistant ink instead of ordinary light pack ink. The layout design should be designed with a transparent edge of 2mm or more for edge sealing. If the entire design is for a pattern, it should be designed with a white ink layer under the color ink as much as possible.

复合工序：使用的无论是无溶剂还是普通溶剂型胶水，一定是需要耐温的，而不能使用普通轻包材质性质的胶水，否则，拉链头位置容易出现高温离层现象。

Composite process: Whether using solvent-free or ordinary solvent based adhesives, they must be temperature resistant and cannot use ordinary lightweight adhesive materials. Otherwise, the zipper head position is prone to high-temperature delamination.

底层材料：选择稍微低温型的材料，同样拉链材质也尽量使用低温型材料，以便更好地配合面料材质BOPP或哑光OPP面料本身不是太耐温的特点。

Bottom material: Choose slightly low-temperature materials, and also try to use low-temperature materials for zipper materials to better match the characteristics of BOPP or matte OPP fabrics that are not very temperature resistant.

②PET或NY钢性材质类拉链袋

② PET or NY steel material zipper bags

由于面料材质属于钢性材料，本身属于耐温材料，封边耐温性非常优良，但是这仅仅是表层的耐温。对于复合膜而言，还是同样需要选择耐温性油墨和胶水。当然，由于表层耐温，拉链的热封温度区间的选择会有更广的范围。

Due to the fact that the fabric material is made of steel and is itself a temperature resistant material, the edge sealing has excellent temperature resistance, but this is only the temperature resistance of the surface layer. For composite films, it is still necessary to choose temperature resistant ink and glue. Of course, due to the temperature resistance of the surface layer, the selection of the heat sealing temperature range of the zipper will have a wider range.

③中间层为VMPET、铝箔、NY、PET等材质的拉链袋

③ Zipper bags made of materials such as VMPET, aluminum foil, NY, PET, etc. in the middle layer

这种结构是特殊的一类拉链袋，也有一定的生产难度。无论是和面料BOPP或哑光OPP，还是NY或PET结构相匹配，这个含镀铝PET结构的拉链袋，都非常让人头痛。

This structure is a special type of zipper bag and also has certain production difficulties. Whether paired with BOPP or matte OPP fabric, NY or PET structure, this zippered bag with aluminum plated PET structure is very headache inducing.

，镀铝层同面层的复合效果非常考验生产工艺。一旦复合强度太高，镀铝层会产生转移；如果复合强度不够，又会使热封性能减弱，热封拉链头位置容易高温起皱。但这种不属于高温离层。如果复合胶水太强产生镀铝转移，才归于高温离层。因此，对于含有镀铝PET结构的拉链袋，我们需要在镀铝复合强度和拉链位置热封的耐温性之间寻求平衡点。既要求镀铝不会产生转移，也同时能够让热封拉链时，特别是拉链头位置，不会产生高温皱现象，也不会产生高温离层现象。

Firstly, the composite effect of the aluminum plating layer and the surface layer is a very challenging production process. Once the composite strength is too high, the aluminum coating will transfer; If the composite strength is not enough, it will weaken the heat sealing performance, and the position of the heat sealing zipper head is prone to high-temperature wrinkling. But this does not belong to the high-temperature ionosphere. If the composite adhesive is too strong and causes aluminum plating transfer, it belongs to high-temperature delamination. Therefore, for zipper bags containing aluminum plated PET structures, we need to find a balance between the aluminum plated composite strength and the temperature resistance of the zipper position heat seal. It is required that aluminum plating does not cause transfer, and at the same time, it can prevent high-temperature wrinkling and delamination when sealing the zipper, especially at the zipper head position.

因此，我们如何选择胶水就很关键了。目前市场上有很多镀铝专用胶水，很多胶水生产商可以提供非常成熟的耐温聚氨酯胶，也就是复合镀铝材质结构同时具备耐温性质的胶水。

Therefore, how we choose glue is crucial. At present, there are many aluminum plated adhesives on the market, and many adhesive manufacturers can provide very mature temperature resistant polyurethane adhesives, which are composite aluminum plated material structures with temperature resistance properties.

同时，熟化也很重要。熟化主要取决于胶水反应的条件，按常理来说，一般是向相对低温、时间稍长方向来决定熟化工艺。

Meanwhile, maturation is also important. Maturation mainly depends on the conditions of the glue reaction. Generally speaking, the maturation process is determined by the direction of relatively low temperature and slightly longer time.

另一点要特别注意的是，每个供应商的胶水都有所不同，所以企业只能具体问题具体分析，不能一概而论。

Another point to pay special attention to is that the glue used by each supplier is different, so companies can only analyze specific problems and cannot generalize.
