Biscuit tin box has become the preferred packaging method for many brands due to its beauty, durability and strong sealing. However, in today's increasingly stringent food safety standards, consumers are particularly concerned about the safety of packaging materials. A qualified biscuit tin box should not only have a beautiful appearance, but more importantly, it should comply with food-grade safety standards to ensure that the food is not contaminated and remains fresh. In this article, we will discuss in detail the food safety standards of biscuit tin box, sealing and preservation technology, environmental protection printing process.   Food safety standard of biscuit tin box 1. International food-grade packaging certification Food contact grade metal packaging must meet strict human safety and health standards, the requirements for food packaging materials vary from country to country, for example: FDA (U.S. Food and Drug Administration) standards: the requirements of the inner wall coating of the iron box can not contain harmful substances, such as lead, cadmium, etc., and must not affect the original smell and taste of food. EU (European Union) food contact material regulations: stipulate that food packaging materials must not release excessive amounts of heavy metals and chemicals to ensure that food is not contaminated. LFGB (German Food Grade Certification): Stricter than the EU standards, with special attention to the health safety and long term storage of food contact materials. GB (China's national standard for food safety): Specific requirements are made for coatings, printing ink components, solvent residues, etc. for food-grade tin boxes.     2. Inside coating and material requirements of food grade tin box The inner wall of the biscuit tin box usually needs to be coated with a food-grade protective layer to prevent metal from migrating into the food, as well as to prevent moisture and rust. Common food grade coatings include: Epoxy Resin Coating: It can effectively block metal ions and protect food from contamination. However, some epoxy resins may contain BPA, so BPA-Free (Bisphenol A-free) coatings have been favoured in recent years. Polyester coating (PET coating): non-toxic and odourless, strong acid and alkali resistance, suitable for long-term storage of food packaging.     Biscuit tin box sealing and freshness preservation technology 1. Importance of sealing structure Biscuits are prone to moisture and softening, so the sealing of biscuit tin box is crucial. Common sealing designs include: Double folding technology: Double folding treatment at the junction of lid and box body improves airtightness and effectively stops air from entering. Silicone sealing ring: Many high-end branded cookie tins add food-grade silicone ring inside the lid of the tin box, which greatly enhances the sealing effect and prevents the biscuits from moisture and flavour.   2. Biscuit preservation technology In order to extend the shelf life of biscuits, many brands have introduced advanced preservation technologies in their packaging: Nitrogen-filled package: Nitrogen is filled during the encapsulation process to prevent oxidative reactions from occurring in contact with air, which can effectively extend the freshness of biscuits. Desiccant packs or moisture absorbing tablets: they can absorb moisture inside the tin box to avoid mouldy biscuits and keep the biscuits crispy. UV protective coating: Some of the tin boxes are coated with anti-UV coating to prevent the ultraviolet rays in the sunlight from affecting the quality of the biscuits.       Food-grade humour printing process and environmental protection concept 1. Non-toxic environmental protection printing technology The customised and beautifully printed pattern design of biscuit tin box is often the key to attract consumers' purchase desire and brand promotion, but the poor quality ink may contain lead, cadmium and other heavy metals, which pose a threat to human health and safety. Nowadays, there are strict standards on the food grade printing process industry: UV printing: UV curing technology, no solvent residue, no heavy metals, to ensure food contact safety. Water-based ink: low VOC emissions, non-toxic and odourless, will not contaminate food.   2. Environmentally sustainable packaging trends As consumers become more environmentally conscious, biscuit tin manufacturers are beginning to adopt safe and environmentally friendly materials and production processes, such as: Recyclable tinplate: able to be recycled, reducing the consumption of metal resources waste, while greatly reducing the cost, in line with the concept of sustainable development. Food-grade coating: avoid chemical pollution to water, air or soil during the production process, in line with environmental protection policies.   In conclusion, food safety is a top priority for biscuit tin packaging. From material use, coating safety, sealing design, to environmentally friendly printing, manufacturers are continuously improving the safety and functionality of their packaging. As consumers' concern for food safety and environmental protection increases, cookie tin manufacturers will see stricter standards and more opportunities for innovation in the future. For brands, adopting tin box packaging that meets food safety standards not only improves product competitiveness, but also wins consumers' trust.
