Different packaging materials, different requirements.
Such as powder or articles, afraid of contaminated items on the sealing performance requirements are very strict, easy to damp or mildew materials for airtightness also have special requirements. So in the design of ton bag, pay attention to consider the fabric coating process and the effect of the sewing process on the dust.
Tons of bags to facilitate the shipment of bulk powder materials, with a large volume, lightweight and other characteristics, the following jumbo bag factory to introduce the ton bag dust removal process knowledge：
Removal of export tons of bags with cloth surface dust methods are:
1, tons of cloth before importing Composite roll from the delivery frame, or plus Corona impact cloth, decontamination and to oil; or the installation of a wide brush, sweep away dust cloth; or the use of rubber-coated special cleaning roller.
2, Cleaning roller close to the cloth surface, the cloth surface can be transferred to the precipitated powder at both ends of the cloth edge rotation. Thereby reducing the dust due to excessive cloth flour, resulting in the impact of the coating peel strength.
In fact, in practice, the diaphragm gap distance and offset between the two must be combined with other process parameters and flexible applications.
Because for different jumbo bag substrate, the degree of heat absorption, and the ability to resist burns are different.
We can be based on different substrates coated, adjusted from different air gap distance and Offset in different diaphragms, looking for good results.
