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 precipitation and rancidity, preventing pollution, and preventing heat during packaging. Therefore, the requirements for the packaging materials of chocolate are very strict, not only to ensure the aesthetics of the packaging, but also to meet the above 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 material packaging. 1. Paper packaging material for chocolate Due to the high environmental protection of paper products, they are generally used for the outer packaging of chocolate. The outer packaging adopts a fixed carton to protect the chocolate from damage and enhance the display. Chocolate paper packaging involves coated paper, white cardboard, grey board paper, box board paper and corrugated paper, etc. Some high value-added functional papers such as water resistance, oil resistance, acid resistance, deodorization, and wafer paper are gradually increasing. , which will become a highlight of additional attention for paper packaging companies. and this paper packaging is what we can make for you. contact us to get quotation from us, and we make fully customization for you.
Aluminum foil has the characteristics of moisture-proof, light-proof and heat preservation. Regardless of the inside and outside of the chocolate, there must be a shadow of aluminum foil. Under normal circumstances, aluminum foil is used as the inner packaging of chocolate. Chocolate is an easily melted food, and aluminum foil can effectively ensure that its surface does not melt.
This is a kind of traditional packaging material. Because of its good barrier properties and ductility, it has always had a place in the current chocolate packaging. However, due to factors such as production technology, production efficiency, application limitations and prices, it 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 various forms of display. With the maturity of technology, cold-sealed soft packaging has gradually become the most important internal packaging of chocolate due to its high packaging speed, low odor, no pollution, easy tearing, etc. Packaging Materials. The focus of the development direction of plastic packaging in the later period is to improve the performance of existing plastics, develop new varieties, improve strength and barrier properties, reduce dosage, reuse, and classify and recycle to protect the environment.
Composite materials have gradually become a commonly used packaging material in chocolate and candy because of their composite characteristics of various materials and obvious protection and display capabilities, easy to obtain materials, simple processing, firm composite layers, and low consumption. Most of the composite materials are based on flexible packaging. At present, the commonly used materials are paper-plastic composite, aluminum-plastic composite and paper-aluminum composite. The inner packaging is compounded with PET and aluminum foil to maintain the luster, fragrance and shape of the product, moisture-proof and oxidation-proof, prolong the shelf life and protect the product performance.
These are the most common packaging design materials for chocolate. According to the different packaging styles, there are also container-type 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 material it is, it is designed to protect chocolate products, improve product hygiene and safety, and improve consumer purchasing desire and commodity value. So do a thorough investigation when choosing chocolate packaging materials.
