Why does sulfur-free paper wrinkle?
For many sulfur-free paper manufacturers, the common problem is the wrinkling and deformation of the sulfur-free paper, which is also a problem with more customer complaints. However, in many cases, the wrinkles of the sulfur-free paper are not caused by the quality of the sulfur-free paper itself. It is more caused by external factors. Today, let Sulfuric Paper Wholesale Manufacturer explain in detail the causes of wrinkling of sulfur-free paper.
Sulfur-free paper The main cause of deformation is moisture in the paper. Sulfur-free paper is composed of plant fibers, so sulfur-free paper has strong dehydration and water absorption. Whether dewatering or absorbing, will cause sulfur-free paper deformation and wrinkling. This is why the moisture content is one of the important factors to measure the quality of sulfur-free paper.
When the moisture content of sulfur-free paper and kraft paper changes, the paper fibers will expand or contract due to water absorption and dehydration. When water is absorbed or dehydrated, hydrogen bonds will also change the binding force, thereby deforming the sulfur-free paper.
Sulfur-free paper has strong water absorption and can easily absorb moisture and moisture in the case of improper packaging and storage. Sulfur-free paper typically becomes brittle and curled when subjected to moisture absorption and dewatering. Therefore, it is necessary to control the humidity of the warehouse environment when storing sulfur-free paper.
The humid climate in different areas is in different states, so moisture-proof measures should be taken according to the local climate. So how should sulfur-free paper take moisture-proof measures?
For sulfuric acid paper wholesale manufacturers, they should pay attention to three aspects: storage, storage, delivery.
The sulfur-free paper produced should be quickly moved to the warehouse for storage, and should not be placed in the open air, otherwise it will cause unnecessary losses.
When storing, control the air humidity, close the doors and windows, and fold the tray when placing the tray to prevent the paper tube from directly touching the ground.
When transporting, sulfuric acid paper wholesale must strictly check the condition of the paper to avoid sending defective products to customers. Therefore, moisture-proof work is also a top priority.
