Description

Technical Field

[0001] The present invention relates to the technical field of waxed paper box production, and specifically provides a microporous waxed paper box production system and method based on disordered hole punching by multiple needle rollers. Background Art

[0002] During food processing, especially in the production of frozen foods such as fish and chicken, the selection of packaging materials and their functionality have an important impact on product quality and production efficiency. Traditional frozen food packaging usually uses ordinary waterproof paper boxes or plastic boxes, but these materials have many problems during the freezing process. Generally, traditional frozen food packaging is produced by a waterproof paper box production system. Although the ordinary waterproof paper boxes produced by the current waterproof paper box production system can prevent water penetration, their air permeability is poor. As a result, during the high-pressure freezing process of frozen foods in a plate freezer, the internal gas cannot be effectively discharged, easily forming air gaps or uneven local freezing, which affects the forming quality and appearance integrity of the food.

[0003] For the waxed paper boxes produced by the current waterproof paper box production system, some frozen food packaging uses waxed paper boxes to enhance waterproof performance. However, conventional waxed paper boxes lack air permeability design and cannot meet the gas discharge requirements during the block freezing production process. Especially under the pressure of a plate freezer, if the packaging material does not have air permeability, the gas between the food and the packaging cannot be discharged in time, easily leading to problems such as loose frozen forming, irregular shape, or uneven surface. In addition, if the packaging material is completely frozen and adhered to the food, it will not only increase the demolding difficulty but may also cause food damage due to forced separation, affecting the product qualification rate. Summary of the Invention
