I. Analysis of the status quo of food packaging technology

     In view of the wide variety of foods, the wide variety, and the endless emergence of organic substances, which are susceptible to external microbial infections and physical, chemical, mechanical and other adverse effects, most require packaging to have strong protection, use and promotion functions, resulting in food. Sterility, miniaturization, diversification, simplification, mechanization, and automation of packaging have become the mainstream of the times.

     Regardless of the method of packaging, we must first select the packaging materials and packaging containers from the requirements of all aspects of the inner packaging.


     For liquid foods, commonly used plastic bottles, glass bottles, metal cans, bags made of composite materials, boxes, cups, etc.; for semi-fluid foods, commonly used plastic or glass jars, bags, boxes, cups, etc. made of composite materials; For powders, granules and foods mixed with liquids, common metal cans, plastic jars, bags, boxes, cans made of composite materials, etc.; for individual or multiple collections of blocks, sheets, strips And similar to spherical, hemispherical and other solid foods, commonly used in larger plastic boxes, metal cans, bags made of composite materials, trays, boxes and so on.

     In short, the current food sales packaging containers, bottles, cans, boxes, etc. made of metal and glass account for a small proportion, and there is a gradual decline trend, mostly used for gift packaging or special packaging. Boxes, trays, etc. made of thin cardboard are generally used for outer packaging due to poor barrier properties. Only bags, boxes, cups, etc. made of composite materials based on plastic film can fully protect the food and beautify the appearance, and have various shapes, easy processing, resource saving, low cost, light weight and adaptability. It can be said that it is almost all-inclusive (usually except for gas and liquid materials), and it is omnipotent (expanding to all occasions in land, sea and air), and it has a promising future.

    Second, the future demand for food packaging

     With the acceleration of people's daily work pace, the richness of nutrition and health food, and the awareness of environmental protection, many new requirements will be put forward for food and food packaging machines in the future. What is striking now is that, given the rapid spread of refrigerators and microwave ovens, and other related conditions, it will not be long-term, and it is possible to develop frozen foods as convenience foods and fast foods into households and enterprises (including services). , tourism and other industries). At the same time, it is necessary to vigorously develop new technologies and new products such as vacuum packaging, vacuum air-packing and aseptic packaging according to local conditions, so that it can be combined with quick-frozen packaging to jointly promote food packaging to a higher level. In this way, consumers at all levels are hoping for small packaging containers for food packaging, especially for the comprehensive understanding of the problem of light weight. It mainly means that the packaging is easy to open, randomly placed, and can be sealed multiple times. It can be collected after use, safe and reliable. Therefore, it is necessary to adopt corresponding measures to further improve the bag type and the box type and realize the scientific and diversified structure of the main body and the sealing structure.

     It is widely recognized that in business competition, quality and cheapness must always be taken into consideration. If you can really do this, it is not difficult to occupy the market and be invincible. One of the ways out is to achieve a dialectical unity of rational packaging and simplified packaging. The reason is obvious, and the simplification is reasonable, but the simplification is not necessarily reasonable (such as the bare plastic tube packaging of the beverages that have been eliminated in the past, the biscuit carton packaging, etc.). In fact, from the mainstream, many well-designed and popular bags and boxes have the advantage in this respect, because the packaging form and structure and related processes and equipment can be greatly simplified, which can greatly reduce the production and sales process. All kinds of consumption waste, and eliminate the occurrence of many stable factors, thereby improving the overall efficiency, and ultimately reflect the general direction of modern packaging.


     Third, the status quo of food packaging machinery

     Still in terms of food packaging, the most common and basic packaging methods available today are two types, namely, filling and wrapping. The filling method is suitable for almost all materials and packaging containers. Specifically, for liquids, powders, and granules with good fluidity, relying mainly on their own gravity, it is necessary to complete the packaging process with a certain mechanical effect. For semi-fluid or larger single-piece and composite parts with strong viscosity, the corresponding pressing, pushing, pick-and-place and other mandatory measures should be adopted. As for the wrapping method, it is different from this. It is mainly suitable for single-piece or assembly with regular shape, strong stiffness and tight packaging, and flexible plastic and composite materials (some additional) Lightweight pallets, liners), wrapped by mechanical action. So far, the wrap form is also rich and colorful, but the bag type should be the mainstream. Observing the domestic and international markets has been inspired, although the filling method and the wrapping method have their own characteristics, but the former is used more powerfully in the world and plays a leading role. Nevertheless, it is worth emphasizing that, in conjunction with the aforementioned advantages of bags and boxes, if the two methods of filling and wrapping can be used together, it can be said that it will enhance the overall function of the food packaging machinery. More effective and all-encompassing. For more than ten years, the international packaging industry has attached great importance to improving the general capabilities and multi-functional integration capabilities of packaging machinery and the entire packaging system, providing timely and flexible production methods for diversified products in the market. At the same time, based on the actual needs of rationally simplifying the packaging and the preferred packaging process, the company has continuously explored and significantly accelerated the pace of its own technological innovation. In particular, it echoes the simultaneous development of modern automatic machine tools and gradually becomes clear. To build a diverse, universal, and versatile integration
