Heavy-Duty Carton Reinforcement

Cardboard shirt inserts are made of high-strength multi-layer plywood with a thickness of 8-15mm, offering high hardness and wear resistance, which can withstand more than 100kg pressure without deformation. Used as the bottom or side support of cartons, they improve the overall load-bearing performance of cartons by 3-5 times.

Heavy-Scenario Customization

Cardboard shirt inserts support customization of length and width according to carton size. Slotting and drilling can be customized for convenient fixing with cartons, and anti-corrosion treatment is provided to extend service life, adapting to the supporting needs of heavy cartons.

Heavy Product Adaptability

Suitable for carton packaging of heavy products such as heavy industrial products, building materials, and large equipment accessories, cardboard shirt inserts are used as carton reinforcement supports, meeting the needs of forklift loading and unloading, container stacking, long-distance sea shipping, and other scenarios, improving carton load-bearing capacity.

Summary: High-strength materials improve carton load-bearing capacity, anti-corrosion treatment extends service life, and customization adapts to heavy scenarios, making cardboard shirt inserts a core accessory for reinforcement and protection of heavy cartons.
