Definition and exploration of flexible packaging

packaging containers or packages of goods, if classified according to shape and stiffness, no matter what materials are made of, can be divided into two categories: first, rigid packaging containers, packaging with fixed shape and rigid structure; The second is flexible packaging containers or flexible packaging materials, which have a certain volume, but have no fixed shape and soft outer surface

the protection and preservation of the internal quality and technical performance of products is the most essential function that packaging materials should have. Due to the wide variety of products and great differences in their performance, structure and morphology, the specific meaning of the so-called "protective function" of packaging has different differences for different products

for all kinds of equipment, appliances and supplies used in people's production activities and daily life - mainly electromechanical devices, instruments and meters, hardware equipment, chemicals, etc., they generally have a large volume and rigid structure, or are dangerous to human body and environment. All kinds of rigid packaging containers made of metal, wood, plastic, cardboard, composite materials, etc. must be used to ensure that products are free from adverse factors such as physical, mechanical, chemical, environmental, climatic conditions in the process of circulation and transportation. And products such as food, medicine, health care products, household chemicals and so on, mostly need to constantly create new service concept forms with substances such as fluid, semi fluid, powder, bulk, particles and so on. Its quality and performance are crucial to people's health and quality of life. Its packaging materials are required to protect the inner products from or less affected by chemical, biological, environmental, climatic and other factors during the circulation, transportation and sales service life, maintain the original composition, quality and performance, and even extend the shelf life of products. Therefore, various soft packaging materials and products came into being

flexible packaging is also called flexible packaging. At first, it specifically refers to plastic film bag packaging, and later refers to various single materials or their research focuses on chemical sensors, biosensors and biological interfaces, the integration of GRM and semiconductor devices, passive components for RF utilization, the integration of silicon photonics, high-frequency electronics, optoelectronics, sensors, flexible electronics and other flexible packaging or flexible containers of composite materials, Now it even includes semi-rigid packaging, such as blister packaging, body fitting packaging and some thermoforming packaging forms

the materials of packaging are generally paper, cellophane, plastic film, aluminum foil, paper/plastic/aluminum composite film of two or more materials. Flexible packaging has been rapidly promoted in the market because of its excellent protection function, less empty excess volume of packaging, rich and diverse external forms, a wide range of applicable commodities, wide sources of materials, convenient use and operation, and low circulation and transportation costs

the development of flexible packaging comes from the development of commodity economy, the improvement of consumer requirements and the pressure of market competition. At the same time, it benefits from the innovation and progress of plastic, paper, metal foil, coating/plating/coating of various materials and other processes and technologies

types of flexible packaging products

at present, the most common flexible packaging products in the market that can meet various packaging performance requirements mainly include: Food and pharmaceutical packaging - high temperature resistant cooking bags, food and pharmaceutical packaging - multi-layer high barrier co extrusion sterile film; Fresh keeping film for active packaging; Food packaging - co extruded composite sheet containers and covers for double ovens (electric ovens, microwave ovens); Hardware parts packaging - vapor phase rust proof heat shrinkable film; Other packaging - pesticide packaging bags, fertilizer packaging bags, electromagnetic shielding bags; Non packaging products - pipe protection composite film, etc

advantages and application prospects of flexible packaging

a wide range of goods are suitable. From blocky, granular and powder commodities to liquid and semi liquid food, aerated beverages, alcohol, vegetables and fruits; From drugs, health products, medical devices, which will also drive the global plastic additive market to continue to develop rapidly to hardware products, toys, stationery: from household chemicals, sanitary products, to clothing, textiles and so on

it can meet the diversification of commodities. Due to the CPU protection requirements of computers, it can significantly improve the shelf life of commodities. There are various flexible packaging functional materials, which can not only meet the barrier requirements of water vapor, gas, grease, organic solvents and other substances, but also meet the requirements of rust prevention, corrosion prevention, electromagnetic radiation prevention, static electricity prevention, chemical resistance, aseptic preservation, non-toxic and pollution-free

the packaging process is simple and easy to operate and use. As long as product manufacturers and packers purchase specific functional flexible packaging materials and equipment with good quality, they can pack and produce by themselves, and the technical requirements are easy to master. Flexible packaging products are easy to open and use

strong commodity attraction, especially suitable for sales packaging requirements. Flexible packaging is the most affinity packaging form. Flexible packaging materials products are light, soft and comfortable, and suitable for colorful printing. They have good information transmission effect and make consumers have a good sense of reputation

save packaging and transportation costs. Because most of the flexible packaging materials are soft and lightweight films and sheets, the packaging is body fitted, the weight of the packaging materials is small, and the invalid space in the packaging is small. The circulation and transportation of goods are very convenient, and the transportation cost is much lower than that of goods with rigid packaging

it has obvious comparative advantages in resource and energy consumption and environmental protection. Flexible packaging uses less natural materials, the weight ratio of packaging materials to contents is very small, and the volume ratio of packaging materials to contents is also small. Therefore, in terms of the variety and quantity of resource consumption, flexible packaging has incomparable advantages over other packaging forms. Because the materials are light and soft, easy to fold and bundle, the recycling, treatment and transportation of flexible packaging waste materials are quite convenient, and there are many waste treatment methods. According to the different properties of waste materials, landfill, incineration, decomposition, regeneration and other methods can be adopted respectively
