As an important material in the field of food packaging, food cardboard has many unique characteristics, which make it play a key role in ensuring food safety and improving packaging quality.
In terms of raw materials, food cardboard is usually made of pure wood pulp, and the quality of raw materials is strictly controlled. On the one hand, it does not contain harmful substances, such as fluorescent agents, heavy metals, etc., which fundamentally guarantees food safety and avoids food contamination when in contact with food; on the other hand, the raw materials are carefully screened and processed during the production process to ensure that the paper is free of impurities and odors, and to ensure food quality and taste.
Excellent physical performance. It has high burst resistance, can withstand certain external impact and pressure, and effectively protects food from damage during packaging and transportation; the paper has good stiffness and is not easy to deform, which makes it easy to process into various food packaging containers and maintain the shape and structure of the packaging; the thickness is uniform, which not only provides sufficient strength and protection performance, but also takes into account packaging convenience and cost.
Food cardboard has excellent printing suitability. Its surface is highly flat and absorbent, which can present clear and bright printing effects, making it convenient to print food-related information on the packaging, improving the packaging grade and publicity effect; it is also easy to cut, fold, bond and other processing operations, and can make complex packaging structures.
In addition, it has waterproof and other functions, and can prevent food from being affected by moisture after special treatment; it meets the food packaging hygiene standards and has high safety and reliability.
It is precisely because of these characteristics that food cardboard has a wide range of applications and can be used to make food packaging boxes, food bags, placemats, paper cups, etc., especially in high-end food packaging.
