Transparent plastic boxes are typically made from coated paper, matte paper, or super double-coated paper; another option is foil packaging. Foil is a soft metal film that is not only moisture-proof, airtight, light-proof, wear-resistant, fragrant, and odorless, but also, thanks to its elegant silver sheen, it is easy to process into beautiful patterns and markings in various colors, making it more popular among consumers.
Until now, it has been discovered that foil has shielding properties, paper has strength, and plastic has heat-sealing capabilities. The combination of foil, plastic, and paper further enhances the barrier functions of packaging materials, necessary to block moisture vapor, air ultraviolet rays, and bacteria.
Moisture-Proofing Techniques for Transparent Plastic Boxes
XiaYa Film: Separation film is commonly used in interior decoration, similar to producing pre-printed gift box tissues, paper boxes, tote bags, cover images, and other products.
2. Polishing: A common skill in the post-printing processing of packaging products. After the product surface is polished and varnished, it enhances the moisture resistance, sun protection, and anti-curling properties of the printed items. Additionally, it can also develop the outer color intensity of the product, significantly enhancing its depth of field.
3. Spray Coating: In recent years, with the continuous development trend of the commercial economy system, there will be an increasing demand for coated paperboard in liquid beverages, solid chilled foods, and other products, and the professional skills for coating have also become more mature.
4. Wax Coating: The professional skill of waxing on cardboard surfaces is straightforward, both in terms of production and machinery expertise. The actual operation of handling clear plastic boxes is also relatively easy to master.
