Important Factors of Corrugated Cardboard's Quality of Punching Resistence (Report‪)‬

1. INTRODUCTION Corrugated cardboard is defined as cardboard made of one or more layers of paper used for a wave and glued between two or more single--or multi-layered flat areas (Stricevic, 1983). Corrugated cardboard used for packaging in the food industry must be glued with gluten, not with siliceous glue. Packaging used for overseas transport must be waterproof and corrugated cardboard packaging for frozen products must be resistant to low temperatures (those below 0[degrees]C) and humidity and must not be slippery (Rodin, 1991). In other words, the choice of the type of paper used in corrugated cardboard manufacturing will largely depend on the packaging type (transport or commercial). High-grammage paper types are used for making transport packaging, while low-grammage ones fit commercial packaging better.
