Flexible packaging industry practitioners are more clear, the origin of flexible packaging is through canned products and the extension of substitutes, commonly known as “soft cans”. In the composite flexible packaging products, the most can reflect the soft can of a product is the suction nozzle products.
1. Raw materials
In terms of raw material process design, fabrics must be designed according to the conventional process, and the fabric must be high temperature and pressure resistant. The pressure resistance mainly refers to the pressure and high temperature that can be withstand when the pressure nozzle is pressed. For the suction nozzle bag of a single material, it is more necessary to pay special attention to the temperature resistance of the fabric, otherwise it will be easily crushed. The more favorable the thermal bonding performance of the bag body and the suction nozzle.
2. Printing
Ink needs to use high temperature resistance, especially on the position of the press nozzle, the related ink, if necessary, need to increase the curing agent, to improve the temperature resistance of the pressure nozzle position.
If the product is designed with dumb oil, the position of the pressure nozzle is generally designed in the non-dumb oil position.
3. Composite
Composite needs to use high temperature resistant glue, of course, the high temperature resistance here does not refer to high temperature cooking glue, but suitable for high temperature pressure nozzle glue.
4. Bag making
For manual presser products, special attention should be paid to the size control of the presser position. The general position size of the presser position has a certain size space range.
That’s how the bags are made. Check out our website for more news
