Packaging forms and analysis of fruit and vegetable juice drinks in recent years, fruit and vegetable juice drinks have developed rapidly, and there are a variety of packaging containers, mainly including the inherent strength of glass polyurethane materials, and further strengthened containers, metal containers, plastic containers, paper-based composite containers, plastic composite film containers, etc. can be obtained by using metal veneers to form a composite structure

glass is a kind of packaging material with a long history. The glass container has a flexible, beautiful and colorful decorative effect; High chemical stability, good barrier, airtight, easy to seal, safe and non-toxic; Rich raw materials, low price, recyclable; High degree of production automation. However, the glass bottle is bulky and fragile, which is inconvenient for turnover and transportation

metal containers mainly include two-piece cans and three piece cans. Most of the three piece cans are made of tinplate, and most of the two piece cans are made of alloy. Three piece cans are mainly used for fruit and vegetable juice drinks. Metal containers have many advantages: they have excellent barrier performance, which can not only block gas, but also light, which makes fruit and vegetable juice drinks have a long shelf life; It has excellent mechanical properties, mainly in high temperature resistance, humidity resistance, pressure resistance and insect resistance; Not easy to be damaged, easy to carry; Good surface decoration, which can stimulate consumption; It can be recycled. However, the poor chemical stability of metal cans and the poor quality or technology of inner coating will make the fruit and vegetable juice drinks change color and taste; The economy is also poor

the main types of plastics used for fruit and vegetable juice beverage packaging are: polyethylene, polyvinyl chloride, polypropylene, polyester, polyvinylidene chloride, etc. Polyester (PET) material is widely used in the packaging of fruit and vegetable juice drinks due to its light material, colorless and transparent, high strength, good surface gloss, glass like appearance, strong plasticity and mechanical properties, non-toxic, tasteless and odorless, good air tightness, low molding shrinkage, small expansion coefficient, moderate material cost and other advantages

paper based composite containers are made of paper and plastic film, or multilayer composite flexible packaging materials with aluminum and platinum. This kind of material has the advantages of high barrier, high strength, good heat sealing, low temperature preservation, light weight, saving stacking space, convenient circulation and consumption, etc. However, it is difficult to dispose and recycle the waste, which is easy to cause environmental pollution

the plastic composite film container is made of two or more layers of the same or different plastic films bonded together, which overcomes the shortcomings of a single material and has the properties of high moisture resistance, oxygen isolation, fragrance preservation, light shielding, etc. However, the environmental pollution caused by its packaging waste restricts its application

all kinds of packages have their own characteristics. With different packaging, the matters needing attention in the production and sales of fruit and vegetable juice drinks are also different. For example, the inner coating of the iron can must pass the standard, otherwise the acid components in the fruit and vegetable juice will react with the tank body, affecting the color and flavor of the product, and the acidity should be avoided during storage. 5. The maintenance personnel and maintenance department should ensure that the substances in the can contact with the tank through three inspections and one handover (self inspection, mutual inspection, full-time inspection and one handover are qualified); PET bottles should not be exposed to strong light, because light will accelerate the change of pigment in beverages
