Common materials for paper bags include: white cardboard, kraft paper, coated paper, and specialty paper. When making tote bags, merchants usually print patterns and advertising slogans on the paper bags, and then use a lamination process. Only after lamination can the patterns on the paper bag last longer, and the paper bag will be more durable.

Lamination refers to applying a transparent plastic film to the surface of the printed material through heat pressing, which protects the material and increases its gloss. Lamination is a major post-printing process, requiring a clean, flat, clear, wrinkle-free, and bubble-free surface.

Lamination protects the paper bag from wear and tear, makes the printed patterns brighter, and prevents damage, thus extending the tote bag’s lifespan. At the same time, the plastic film also provides protection against moisture, water, stains, abrasion, folding, and chemical corrosion.

Different lamination processes produce different effects. Matte lamination will make the paper bag’s color slightly darker than before lamination, giving it a more stable and elegant appearance, while glossy lamination will make the paper bag appear more vibrant and bright.

Lamination technology is widely used in the printing industry. Common laminated packaging products include cartons, boxes, tote bags, and self-adhesive labels. REENYOUNG is a professional paper bag customization manufacturer. If you have any customization needs for tote bags, please contact us.
