Does food-grade kraft cardboard help maintain the freshness and ventilation of food?
Food-grade kraft cardboard is a packaging material with good air permeability. Its unique properties help maintain the freshness and ventilation of food, thereby promoting long-term preservation of food. The following will expand its characteristics in detail from three aspects: breathability, freshness preservation and ventilation.
The breathability of food-grade kraft paperboard makes it an ideal packaging material. Breathability refers to the ability of substances to pass through a material, and kraft board manufacturers create kraft board that allows air and moisture to flow freely inside and outside the packaging due to its natural fiber structure and microporous properties. This breathability allows the air inside the package to circulate, preventing premature spoilage or odor generation of food, thereby maintaining the original taste and quality of the food.
Food-grade kraft cardboard has a significant effect on food preservation. The breathability allows the air inside the packaging to maintain circulation, prevents the food from getting damp or moldy, and extends the shelf life of the food. Especially for some foods that are susceptible to moisture or oxidation, such as flour, pastries, etc., the use of food-grade kraft cardboard packaging can effectively reduce the possibility of food deterioration and maintain its freshness and nutritional value.
Food-grade kraft cardboard also has good ventilation. Ventilation refers to the ability of air to flow through a material, and the microporous structure of kraft cardboard allows air to circulate freely inside and outside the packaging. This ventilation helps reduce the temperature and humidity of the air inside the package, slow down the spoilage of food, and maintain the taste and freshness of food.
Food-grade kraft paperboard has unique advantages in the field of food packaging due to its good air permeability, freshness retention and ventilation. It can not only effectively protect the quality and nutrition of food and extend its shelf life, but also improve the environmental protection performance of packaging, meeting the needs of modern consumers for safe and healthy food packaging. Therefore, when choosing food packaging, food-grade kraft paperboard has become one of the first choices for many food production companies and consumers.
Is food-grade kraft cardboard less harmful to food than ordinary cardboard?
Food-grade kraft paperboard is a material widely used for packaging food. It is usually made of natural fiber raw materials, such as plant fiber and paper pulp. In contrast, regular paperboard may use recycled pulp or raw materials containing chemical additives. There are obvious differences between these two types of cardboard in production technology, performance characteristics and uses.
Food-grade kraft cardboard is a material specially used for packaging food. Its production process is carried out in strict accordance with food safety standards to ensure that it will not cause contamination or harm to food. It usually uses natural plant fibers, such as wood pulp, bamboo pulp, etc. These raw materials have good degradability and environmental friendliness, and meet the requirements of modern society for sustainable development. Due to the advantages of its natural raw materials, food-grade kraft paperboard will not release harmful substances when it comes into contact with food, which is safer for human health, especially for children and pregnant women.
Ordinary cardboard may use recycled pulp or raw materials containing chemical additives. Recycled pulp usually comes from recycled paper or waste paper. Although it has certain advantages in resource utilization and environmental protection, its quality and performance are often not as good as fresh pulp, and it is prone to problems such as unstable quality and brittleness. In addition, paperboard containing chemical additives may release volatile organic compounds (VOCs) and other substances harmful to human health, which poses certain risks in the field of food packaging.
Food-grade kraft paperboard is widely used in the food packaging industry due to its natural raw materials and strict production standards. It has good water resistance, wear resistance and pressure resistance, which can effectively protect the freshness and quality of food, and is also in line with the concepts of environmental protection and health. In daily life, we can often see food-grade kraft cardboard bags, boxes and other packaging materials, such as bread bags, fruit and vegetable packaging boxes, etc. They protect food while also conveying concern for health and environmental protection.
