Introduction to five common chocolate packaging materials

Introduction to five common chocolate packaging materials

        Due to the characteristics of chocolate itself, it is required to meet the requirements of preventing moisture absorption and melting, preventing aroma escape, preventing oil and fat from rancidity, preventing pollution, and preventing heat during packaging. Therefore, the requirements for chocolate packaging materials are very strict. It is necessary to ensure the aesthetics of the packaging and to meet the above-mentioned packaging requirements. The packaging materials for chocolate appearing on the market mainly include paper product packaging, aluminum foil packaging, tin foil packaging, plastic flexible packaging and composite packaging.

　1, paper product packaging

　　 Due to the high environmental protection of paper products, it is generally used for the outer packaging of chocolate. The outer packaging uses a fixed carton to protect the chocolate from damage and enhance the display. Chocolate paper packaging involves coated paper, white cardboard, grayboard, boxboard and corrugated paper. Some high value-added functional papers such as water resistance, oil resistance, acid resistance, deodorization, wafer paper, etc., are gradually increasing. , This will become a bright spot that paper packaging companies pay more attention to.

       2, aluminum foil packaging

　　Aluminum foil has the characteristics of moisture-proof, light-proof and heat preservation. No matter whether the chocolate is inside or outside, there must be the shadow of aluminum foil. In general, aluminum foil paper is used as the inner packaging of chocolate. Chocolate is an easy-to-melt food, and aluminum foil can effectively ensure that its surface does not melt.

　　3， tin foil packaging

This is a type of traditional packaging material. Because of its good barrier properties and ductility, it has always occupied a place in the current chocolate packaging. However, it is affected by factors such as production technology, production efficiency, application limitations, and price, and is affected by packaging such as plastics. Great impact.

　　4, plastic flexible packaging

　　Plastic packaging has gradually become one of the most important packaging materials for chocolate due to its rich functions and diverse display power. With the maturity of technology, cold-seal soft bags have gradually become the most important part of chocolate due to their high packaging speed, low odor, no pollution, easy tearing, etc., and can avoid the impact of high temperature during the chocolate packaging process. Packaging Materials. The focus of the later development of plastic packaging is to improve the performance of existing plastics, develop new varieties, improve strength and barrier properties, reduce dosage, reuse, and sort and recycle to protect the environment.

　　5, composite material packaging

　　 composite materials have multiple material composite characteristics and obvious protective display capabilities, easy to obtain materials, simple processing, strong composite layers, low consumption, and gradually become a commonly used packaging material in chocolate and candies. Most of the composite materials are based on flexible packaging. Currently, commonly used materials include paper-plastic composite, aluminum-plastic composite, and paper-aluminum composite. The inner packaging is laminated with PET and aluminum foil to maintain the product's luster, fragrance, shape, moisture and oxidation resistance, extend shelf life and protect product performance.

　　 These are the common packaging design materials for chocolate. According to the different packaging styles, there are also container packaging on the market, which need to be made of metal materials or used in combination with composite materials. No matter what kind of packaging materials are used to protect chocolate products, improve product hygiene and safety, and increase consumers' desire to buy and product value. So make a thorough investigation when choosing chocolate packaging materials.
