At present, except for a few low-end products and individual brands on the market, most brands have their own exclusive packaging design, which is not only conducive to raising product prices, but also to stand out from competing products and create better benefits.
1 Main types of wine packaging materials
Wine packaging is mainly divided into outer packaging and inner packaging. The types of outer packaging materials include paper, plastic, metal and wood; the types of inner packaging materials include plastic, glass, wood and ceramics; as some brands become more and more famous, they will be specially provided for some dignitaries. The packaging of the wine is also very innovative, and some use ceramics, crystals and even jade. Today, let’s learn about the influence of the packaging material in the wine bottle on the quality of wine.
1.1 Influence of the inner packaging material of wine on wine
The “inner packaging” of wine refers to the packaging material that is in direct contact with the wine. The characteristics of this type of packaging material are short-term stability, but the mellow aroma of wine needs to be stored for a long time. The long-term contact between wine and wine packaging materials will affect the quality of wine. When food containers, packaging materials, etc. come into contact with food, over time, some of these substances may migrate to the food, affecting even Change the taste or quality of food, thereby affecting food safety.
1.3.2 Glass is mainly made into wine bottles, which are transparent, hard and pressure-resistant, have good barrier, corrosion resistance, heat resistance and optical properties, and can be used for various forming and processing methods to make wine of various shapes and sizes. bottle, but in order to facilitate glass forming, oxides need to be introduced into the glass.
① It can form oxides of glass alone, and become glass formers (network formers) oxides;
②Oxides that cannot form glass by themselves but can change the properties (or structure) of the glass, become oxides that change the body (outside the network), such as Li2O, Na2O, K2O,
CaO, MgO, BaO, etc.;
People rely on food for the sky, and food safety is closely related to every consumer, and food safety has become a focus of attention. With the continuous improvement of people’s living standards and the rapid development of science and technology, people’s focus on food safety is not only limited to the problem of food itself, but also the food safety problems that may be caused by materials and products that come into contact with food have become increasingly popular. One of the things to pay attention to. The most typical times, such as special rich coatings, benzene-based solvents in food packaging bags, and other safety issues have aroused widespread concern and concern from all walks of life.
Among the wine packaging materials, glass wine bottles are used as containers, and their use has been relatively mature. Ceramic wine bottles will deteriorate due to factors such as porosity and water absorption. Bone china has low water absorption and small porosity, and can be used in wine packaging. The plastic products mentioned above have been widely used in wine packaging, but they all have their own advantages and disadvantages, and a composite material that blends two or more polymer materials can make up for the deficiencies in the application of various polymer materials. As a scientific research institution, it should strengthen the research and application of new wine packaging materials, find suitable packaging materials, provide better professional titles for the development of the wine industry, and allow the long-standing wine culture to spread on the land of China.
