[Chinese Packaging Network News] due to its own characteristics of chocolate, in the packaging requirements of anti-hygroscopic solubilization, anti-aroma escape, prevent grease rancidity, anti-pollution, heat and other requirements. Therefore, the requirements for packaging materials for chocolate are very strict, and it is necessary to ensure the aesthetics of the packaging and also to achieve the above-mentioned packaging requirements. The packaging materials for chocolate appearing in the market mainly include paper product packaging, aluminum foil packaging, tin foil packaging, plastic flexible packaging and composite material packaging.
First, paper product packaging
Due to the high environmental protection of paper products, it is generally used for the packaging of chocolate. The outer package uses a fixed carton to protect the chocolate from damage and enhance display. Chocolate paper packaging involves coated paper, white paperboard, grey paperboard, linerboard and corrugated paper, etc. Some water-resistant, oil-resistant, acid-proof, deodorant, wafered paper and other high-value-added functional papers are gradually increasing in use. This will be a bright spot for paper packaging companies to pay extra attention.
Second, aluminum foil packaging
Aluminum foil is moisture-proof, light-proof and heat-insulating. Whether the chocolate inside or outsourcing must have the shadow of aluminum foil. In general, aluminum foil is used as the inner packaging of chocolate. Chocolate is a facile food, and aluminum foil is very effective in ensuring that its surface does not melt.
Third, foil packaging
This is a kind of traditional packaging material. Because of its good barrier property and ductility, it has always occupied a place in the current chocolate packaging. However, it is affected by factors such as production process, production efficiency, application limitations, and price, and it is covered by plastics, etc. The great impact.
Fourth, plastic flexible packaging
Plastic packaging has become one of the most important packaging materials for chocolate with features such as rich functions and various forms of display power. As the technology matures, cold-seal soft packs are becoming the most important component of chocolate because of their high packaging speed, low odor, non-pollution, and easy tearability, and they can meet the impact of avoiding high temperatures during the chocolate packaging process. Packaging Materials. The focus of the development direction of late-stage plastic packaging is to improve the performance of existing plastics, develop new varieties, increase strength and barrier properties, reduce usage (thick-walled), reuse, and recycle to protect the environment.
Fifth, composite material packaging
Composite materials have a variety of material composite properties and obvious protection and display capabilities, easy to obtain, easy processing, solid composite layer, low consumption, and gradually become a common packaging material in chocolate and candy. Most of the composite materials are based on flexible packaging. Currently used materials include paper-plastic composites, aluminum-plastic composites, and paper-aluminum composites. The inner package is compounded with PET and aluminum foil to maintain the gloss, fragrance and appearance of the product against moisture and oxidation, extend shelf life and protect product performance.
Chocolate packaging design materials are common to these types. According to their different packaging styles, there are packaging containers on the market, which require the use of metal materials or composite materials. No matter what kind of packaging material is to protect chocolate products, improve product health and safety and increase consumer desire to buy and product value. So make a thorough investigation when choosing chocolate packaging materials. Need to know more relevant information, please pay attention to China Packaging Network!
