When doing business in food packaging and exporting packaging products, choosing the right compliant food-grade cardstock is a crucial step. It not only affects the compliance and inspection of the products but also directly influences food safety and customer trust. Many purchasers often struggle with the compliance standards of food-grade cardstock and lack practical purchasing skills. This article, combining industry practices and compliance requirements, clarifies the key points to help everyone accurately select the right food packaging cardstock.
First, let's look at the essential compliance standards for food-grade cardboard. In China, the main basis is the national standard for food contact paper and paperboard, which strictly limits the migration limits of fluorescent brighteners, heavy metals, formaldehyde, and microorganisms, and strictly prohibits the use of toxic and harmful raw materials and auxiliary materials. For foreign trade exports, it is necessary to adapt to the requirements of the target region, such as the EU framework regulation on food contact materials and the relevant food contact regulations of the US FDA. The core safety requirements are consistent: no fluorescence, no odor, and passing relevant migration tests to ensure safe contact with the packaged food. At the same time, the selected cardboard also needs to have corresponding physical properties according to specific usage scenarios, such as necessary stiffness and temperature resistance, and determine whether oil and water resistance treatment is needed based on whether it comes into contact with oil and water, to meet the different packaging needs of baking, fast food, fresh produce, beverages, etc.
When actually choosing food packaging cardstock, it is necessary to avoid the mistake of blindly selecting the type. The first step is to check the qualifications. Be sure to ask for a conformity declaration, a third-party food-grade test report, and a factory-issued quality certificate to avoid ordinary cardstock being passed off as food-grade products. The second step is to look at the material. It is recommended to prefer food-grade white cardstock made of virgin fibers or unbleached natural color food cardstock. If recycled pulp products are selected, it is necessary to confirm that they have complete compliance tests to ensure that the migration amount meets the standards. The third step is to look at the performance. Select the type according to the final use. For baking product packaging, choose a high stiffness type. For liquid and oil-based food, choose a food-grade laminated oil and water-resistant type. For frozen food, choose a low-temperature resistant type that is not prone to cracking, and confirm that the laminated layer also meets food contact requirements. The fourth step is to look at the specifications. Customize the thickness and size as needed, taking into account good printing adaptability to facilitate the printing of logos and patterns in the later stage.
Food-grade cardstock that meets compliance standards and is suitable for various scenarios can not only satisfy domestic and international food packaging compliance requirements but also enhance the packaging texture. Whether it is wholesale purchase or customized production, firmly grasping the two points of standards and practical operation will enable you to select high cost-performance food packaging-specific cardstock.
