Nowadays, business is developing rapidly. A good food packaging bag can not only be perfectly presented with a single design drawing, but also in terms of materials, protection, and good bag making equipment. Here are several points about the design of packing bag.



Must understand food requirements for protection

 

Different foods have different chemical components, physical and chemical properties, etc. Therefore, different foods have different protection requirements for packaging. For example, the packaging of tea should be highly oxygen-barrier (to prevent the active ingredients from being oxidized), high moisture-resistance (wet and mildew of the tea), high light-resistance (chlorophyll in tea will change by sunlight), high-resistance aroma (The aroma components of tea molecules are easy to distribute and lose the taste of tea. In addition, tea also easily absorbs external odors), and a considerable part of the tea on the market is currently packed in ordinary plastic bags such as PE and PP, which greatly wastes the effective ingredients of tea The quality of tea cannot be guaranteed.

 

Contrary to the above foods, there is a choice of respiration after picking fruits, vegetables, etc., that is, the packaging requires different transmission rates for different gases. For example, the roasted coffee beans slowly release carbon dioxide after packaging, and cheese also generates carbon dioxide after packaging. Therefore, their packaging should be highly oxygen-resistant and highly carbon dioxide-permeable. Raw meat, processed meat, beverages, snacks, baked goods, etc. also have very different requirements for protective packaging. Therefore, packaging should be designed scientifically according to the different nature and different protective requirements of the food itself.

Choosing suitable packaging materials

 

Modern food packaging materials are mainly plastics, paper, composite materials (plastic / plastic, plastic / paper, plastic / aluminum, foil / paper / plastic and other types of multilayer composite materials), glass bottles, metal cans Wait. We will focus on composite packaging.

 

Composite material is the most widely used flexible packaging material. At present, there are more than 30 kinds of plastics used in food packaging, and there are hundreds of kinds of plastic-containing multilayer composites. Composite materials generally use 2-6 layers, but special needs can reach 10 or more layers. The use of plastics, paper or tissue machines, aluminum foils and other substrates in a scientific and reasonable combination or lamination can almost meet the packaging requirements of various foods. For example, Tetra Pak milk made from multilayer materials such as plastic / cardboard / aluminum-plastic / plastic can have a shelf life of up to six months to one year. Some high-barrier soft-packed canned meat can have a shelf life of up to 3 years, and some developed country composite packaging cakes have a shelf life of more than one year. After one year, the cake nutrition, color, aroma, flavor, shape and microbial content still meet Claim. Special attention should be paid to the selection of the base material of each layer in the design of composite packaging. The combination must be scientific and reasonable, and the comprehensive performance of the combination of each layer must meet the comprehensive requirements of food for packaging.

 


Using advanced packaging technology methods

 

In order to extend the shelf life of food, new packaging technologies are continuously developed, such as active packaging, mildew-proof packaging, moisture-proof packaging, anti-fog packaging, anti-static packaging, selective ventilation packaging, non-slip packaging, buffer packaging, etc. New technologies are not widely used in China, and some methods are still blank. The application of these advanced technologies can significantly improve the protection function of packaging.

Selection of packaging machinery and equipment supporting food processing technology

 

In order to meet the needs of food processing technology, a variety of new packaging equipment has been developed, such as vacuum packaging machines, vacuum inflatable packaging machines, heat shrink packaging machines, blister packaging machines, skin packaging machines, sheet thermoforming equipment, liquids Filling machines, forming / filling / sealing packaging machines, aseptic packaging equipment, etc. According to the selected packaging materials and packaging technology methods, the selection or design of packaging machinery supporting food processing technology and production capacity is a guarantee of successful packaging.

 


Modeling and structural design should meet scientific requirements

 

The packaging design should meet the geometric requirements, and strive to make a larger volume container with the least amount of packaging materials, which can save packaging materials and meet environmental protection requirements. The structural design of the packaging container shall meet the mechanical requirements, and the compressive strength, impact resistance, and drop resistance shall meet the requirements during the storage, transportation, and sales of the packaging. The shape design of the packaging container should be innovative, such as pineapple juice in a pineapple-shaped container, and lively packaging containers such as apple juice in an apple-shaped container are worth promoting. Packaging containers should be easy to open or open repeatedly, and some require opening or sealing.

 


Brand awareness of packaging and decoration design

 

Packaging and decoration design should be consistent with the preferences and habits of consumers and consumers in exporting countries. The pattern design is best coordinated with the contents. The trademark should be in a prominent place, and the written description should meet the food requirements. The description of the product should be true. Trademarks should be catchy, easy to understand, and easy to spread, and can play a wide role in publicity. The packaging design of brand-name products should be brand-conscious, and some product packages can be easily replaced, which affects sales. For example, a Chinese brand of vinegar has a good reputation in Japan and Southeast Asia, but the sales volume after the replacement of the packaging has greatly decreased because consumers are new to the new the packaging is skeptical. Therefore, a product should be scientifically packaged and cannot be easily changed.
