    With the arrival of the summer solstice, the weather is getting hotter and hotter.
    The first thing everyone thinks of is to buy a variety of beverages to relieve the heat

    .
    But as long as you pay attention, you will find that the beverage packaging on the market is quite different.
    Is there any secret in the choice of beverage packaging materials?
     
    In fact, according to the different materials used, the current beverage packaging on the market mainly consists of polyester (polyethylene terephthalate, PET), metal, paper and glass.
    These four materials have become the " Four major families"

    .
    From the perspective of the family's market share, glass bottles account for about 30%, PET bottles account for 30%, metal cans account for nearly 30%, and paper packaging account for about 10%

    .
     
     
    1.
    Ancient packaging material-glass


    glass is the oldest of the four major families, and it is also the packaging material with the longest history
    .
    Everyone should have the impression that in the 1980s and 1990s, the soda, beer, and champagne we drank were all bottled in glass.
    Even now, glass still plays a decisive role in the packaging industry

    .


     
    A variety of packaging dazzling Figure insect creativity
     
    The glass container is non-toxic and tasteless, and it looks transparent, allowing people to see the contents clearly at a glance, giving people a beautiful feeling
    .
    Moreover, it has good barrier properties and airtightness.
    There is no need to worry about spilling or insects entering after a long time.
    In addition, it is low in price and can be cleaned and disinfected for repeated use.
    It is not afraid of heat or high pressure, and it has thousands of advantages As a result, it is used by many food merchants to serve beverages

    .
    In particular, they fear high pressure, very suitable for loading sparkling beverages, often with beer, soft drinks, fruit juice

    .
    But glass packaging containers also have some disadvantages

    .


     
    Sparkling drinks in glass bottles are very common Tuchong Creative
     
    The main problem is that it is self-heavy, brittle and easy to break
    .
    In addition, it is inconvenient to print new patterns, icons and other secondary processing, and now the amount of use has become less and less

    .
    Nowadays, beverages in glass containers are basically no longer visible on the shelves of large supermarkets.
    Only in places with low consumption power, such as schools, small shops, canteens, and small restaurants, can you see carbonated drinks, beer, and soy milk in glass bottles

    .
     
    2.
    Cans-metal
     
    In the 1980s, metal packaging began to take the stage
    .
    The emergence of metal canned beverages has improved people's quality of life

    .
    At present, metal cans are divided into two-piece cans and three-piece cans

    .
    The material used for the three-piece can is mostly tin-plated sheet steel (tinplate), and the material for the two-piece can is mostly aluminum alloy plate

    .
    Because aluminum cans have better sealing and ductility, and are also suitable for low-temperature filling, they are more suitable for gas-producing beverages, such as carbonated beverages and beer

    .
     
    At present, aluminum cans are more widely used in the market than iron cans.
    Almost all the canned beverages you can see are packaged in aluminum cans

    .
    "Jianlibao" is the first beverage packaged in aluminum cans in the Chinese market.
    I think many people still remember it

    .
    However, the most representative herbal tea beverages in the Guangdong market in China, such as Jiaduobao, Chunhetang, and Denglao herbal tea, are packaged in tinplate cans and have a more solid feel

    .
     
    Speaking of the advantages of metal cans, there are quite a few
    .
    It is not easy to break, easy to carry, not afraid of high temperature, high pressure and air humidity changes, and not afraid of harmful substances

    .
    It has excellent barrier properties, light and gas barrier, can prevent air from entering and produce oxidation reaction, so that the beverage can be stored for a longer time

    .


     
    Jianlibao in old packagingtuchong creativity
     
    Moreover, the surface of the metal can is well decorated, and it is convenient to draw various patterns and colors
    .
    Therefore, most of the beverages in metal cans are colorful, and the patterns are also very rich

    .
    Finally, metal cans are easy to recycle and use, which is more environmentally friendly

    .
     
    However, metal packaging containers also have its shortcomings.
    On the one hand, its chemical stability is poor, and the acidity is too high or the alkalinity is too strong, which will slowly corrode the metal

    .
    On the other hand, if the inner coating quality of the metal packaging is poor or the workmanship is not good enough, it will make the beverage taste bad

    .
     
    3.
    The favorite of dairy products-paper packaging
     
    Early paper packaging generally used high-strength original cardboard
    .
    However, pure paper packaging materials are difficult to use in beverages.
    Almost all of the paper packaging used today is a composite of paper.
    Common paper-plastic composite packaging containers such as Lilebao and Combibloc are common

    .
     
    The polyethylene (PE) film or aluminum foil in the composite paper material can protect from light and air, and will not affect the taste, so it is more suitable for short-term preservation of fresh milk, yogurt and long-term preservation of dairy beverages, tea beverages and Fruit juice and other beverages
    .
    Favorable shape music pillow, sterile square bricks

    .
    However, the pressure resistance and sealing barrier of paper-plastic composite containers are not as good as glass bottles, metal cans and plastic containers, and they cannot be heat sterilized.
    Therefore, the pre-formed carton will reduce its heat due to the oxidation of the PE film during the storage process.
    The sealing performance may become uneven due to creases and other reasons, causing the problem of difficult feeding of the filling molding machine

    .
     
    4.
    It's everywhere-plastic packaging
     
    Plastic packaging is very common in the beverage industry.
    Soda, fruit juice, vegetable juice, herbal tea and other beverages all have plastic packaging products

    .
    If you usually pay attention to the bottom of the plastic bottle, you will find that most of the bottom or the sides near the bottom have the following types of logos

    .
    This is a general international classification of plastics.
    Different numbers indicate plastics of different materials

    .
    At present, there are mainly several types of plastic bottles that are most used in the beverage industry

    .
     
    Plastic PET No.
    1
     
    The full name of PET is polyethylene terephthalate, which is an extremely commonly used resin material and belongs to category 1 in the plastic classification mark
    .
    The plastic bottles of mineral water, juice, and carbonated drinks we usually drink are made of it

    .
    The application ratio of PET bottles in domestic carbonated beverage packaging is close to 60%

    .
     
    No.
    2 high-density polyethylene (HDPE), No.
    4 low-density polyethylene (LDPE)
     
    Both of these are polymers made by polymerizing ethylene as a monomer
    .
    PE is the variety with the largest output among general synthetic resins.
    According to different forms of polymerization, it mainly includes LDPE and HDPE

    .
    The heat resistance of these two materials is not good, and it is easy to melt and deform when heated

    .
    Therefore, try not to use it at high temperatures

    .
     
    No.
    5 polypropylene (PP)
     
    Food grade PP has good heat resistance, so PP is used for microwave-heated lunch boxes, and it is also used for many take-out milk tea and coffee cup lids
    .
     
    Other models
     
    No.
    3 polyvinyl chloride (PVC) is a polymer material made by polymerizing vinyl chloride monomer

    .
    The most common PVC products in daily life are plastic pipes; No.
    6 is polystyrene (PS); the bottled water for drinking fountains uses No.
    7 polycarbonate (PC), but the No.
    7 logo also refers to other good products.
    Several kinds of plastics
