There are many ways to treat the edges of Corrugated cardboard. Here are some common ways:
Unprocessed edges: This is the most basic edge treatment method. The edges of Corrugated cardboard have not been processed in any way and remain in their original state. This processing method is simple and low-cost, but the edges are rough and easily damaged.
Heat sealing edge: The edges of Corrugated cardboard are sealed by heating to improve its edge strength and waterproof performance. Corrugated cardboard with heat-sealed edges is more durable and can effectively prevent moisture intrusion.
Waxed edges: Apply wax or other waterproof material to the edges of Corrugated cardboard to enhance its waterproof and moisture-proof properties. The waxed edge-treated cardboard can effectively resist moisture erosion and improve the durability of the carton.
Embossed Edges: Texture is embossed on the edges of Corrugated cardboard through an embossing machine to improve its friction and grip. Paperboard with embossed edges is more suitable for packaging applications that require holding or stacking.
Glued edges: Apply special adhesive to the edges of Corrugated cardboard to improve its bonding properties and water resistance. Paperboard with glued edges is more suitable for packaging applications that require multi-layer bonding or sealing.
Color printing edge: Color printing or hot stamping and other decorative treatments are performed on the edge of Corrugated cardboard to improve the aesthetics and brand image of the carton. Cartons with color-printed edges are more suitable for gifts, high-end goods and other occasions that require exquisite packaging.
These are common Corrugated cardboard edge processing methods, each processing method has its own characteristics and applicable scenarios. Choosing the appropriate edge treatment method needs to be determined based on the specific needs of the packaging, such as waterproofing, wear resistance, and aesthetics. At the same time, reasonable edge treatment can also improve the overall quality and durability of Corrugated cardboard, thereby improving packaging effects and reducing costs.
