[Resin and Food Related] Introduction of Paper Bags for Customers Troubled by Humidity Issues
[To our customers in the resin and food industries] We would like to introduce paper bags that are resistant to moisture problems!
The contents filled in the paper bag have absorbed moisture and solidified, making them unusable. The molding defects occurred due to the resin absorbing moisture. The above inquiries have been received from many customers, including resin manufacturers and food-related manufacturers. Our company has experience in handling paper bags designed to address moisture issues. This is not just a single item! We will introduce paper bags suitable for various applications. [Paper Bags] ■ Sewn bags + (PE, AL, others) ■ Bottom-sealed bags + (PE, AL, others) ■ Easy-open bags + (PE, AL, others) * PE: Polyethylene film AL: Aluminum composite laminated film Others: Other resin composite laminated films By adding materials other than kraft paper to the inner layer of the paper bag, we can enhance moisture resistance and prevent the contents from absorbing moisture. The effectiveness is achieved by combining regular paper bags with either polyethylene film, aluminum composite laminated film, or other resin composite laminated films. The manufacturing technology for paper bags that combine bottom-sealed bags with aluminum composite laminated film is a technique that only a few companies, including ours, can perform!

basic information
【Understanding the Cause】 Q. Why are paper bags prone to absorbing moisture? A. Paper bags (kraft paper) are made from "wood" fibers, making them natural fibers. Since paper bags (kraft paper) are made from "wood" fibers, they have high moisture absorption and moisture permeability, which ultimately allows moisture to penetrate into the contents. When filling with products that have high moisture absorption, it is safer to avoid using paper bags (kraft paper) alone for the reasons mentioned above.
