Overview of dairy products and packaging (Part 2)

v. packaging of other dairy products

packaging of milk drinks

milk drinks include neutral milk drinks and acidic milk drinks. Sour milk beverage can be divided into fermentation type and blending type. p>

2) plastic bottles: mainly HDPE bottles, PET bottles and BOPP bottles tend to expand

3) composite carton: various brick and roof type packaging

4) metal packaging: mainly cans

cheese packaging

cheese is a kind of dairy product made by coagulating raw milk with rennet or pepsin, and then processing, shaping and fermenting the clot. Cheese has high nutritional value, which is rich in protein, fat, calcium, phosphorus, sulfur and other salts as well as a variety of vitamins, and has a high digestion and absorption rate

whether it is fresh cheese or processed cheese, it should be packed tightly. The preservation of cheese is mainly to prevent mildew and rancidity, followed by maintaining water to maintain its flexible tissue and avoid weight loss

1) hard box packaging

polypropylene sheet forming hard box, sealed with pet/al/cpp materials, with a shelf life of 9 months

2) shrink packaging

uses high barrier co extrusion shrink film and vacuum packaging. The material is eva/pvdc/e-va, with good heat sealing performance and appropriate shrinkage force

3) composite film packaging

composite materials with pa/evoh/pe, pt/pvdc/pe, bopp/pvdc/pe, pa/pvdc/pe and other structures are used for vacuum packaging. It has the characteristics of traditional proportional valve and is packed with deaerator. It is better to pack with CO2

4) single layer plastic film

is packaged with PE, PA, PVC and other single-layer films, which can only be effective for a short time

cream packaging

cream is the milk fat separated from fresh milk. According to its content, it is generally divided into thin cream and cream. Milk fat can be directly processed into delicious flavor foods, such as sweet cream, sour cream, whipped cream, fancy cream and butter. Cream is easy to deteriorate, oxidize and corrupt, and absorb peculiar smell. The requirements for packaging are mainly barrier and fragrance retention

1) composite flexible packaging

is packed with parchment, oil proof paper, aluminum foil/sulfuric acid paper, aluminum foil/oil proof paper and other materials. It can be stored for 9-12 months at a low temperature (2 ℃ - 10 ℃)

2) boxed

first, plastic coated cardboard boxes are packed with capped materials, and second, PVC, PP, PS, ABS and other pressed plastic boxes are packed with capped materials, with a shelf life of more than 12 months

3) metal cans

are used for industrial packaging due to their large weight

the requirements for condensed milk packaging are to prevent microbial pollution such as mold, high barrier and oxidation

1) metal can packaging

the can filling room and containers shall be strictly disinfected, sealed with a vacuum can sealing machine, and the air in the top gap shall be eliminated as much as possible. The storage temperature of sweet condensed milk should not be higher than 15 ℃. After ultra-high temperature instant sterilization, the evaporated milk can be stored at room temperature. The shelf life is about 1 year

2) hose packaging

composite hose is easy to use and carry, and multi-layer composite process provides barrier, such as pe/pet/al/pe structure, so it has a rapid development speed

ice cream packaging

ice cream is a soft mixture made of cream, milk, sugar, eggs, spices and stabilizers, which is frozen after sterilization. Ice cream must be stored under freezing conditions, and the temperature of cold storage (or freezer) should be kept at about -15 ℃. At this temperature, the growth and reproduction of most microorganisms are inhibited, and the biochemical reaction can not be carried out. Therefore, the packaging of ice cream is mainly to solve the problem of secondary pollution in the process of storage, transportation and sales, and the packaging requirements are not high. At the same time, since most cold drinks are stored and sold near 0 ℃, the packaging itself should have cold resistance, and still maintain good toughness and no fracture at low temperature. The requirements for packaging materials include oil extraction resistance and transparency

ice cream packaging mainly includes the following categories:

1) paper: carton and paper cylinder

2) composite films: bopp/pearlescent film, matte bopp/low industry concentration, these problems are pearlescent film, bopp/cpp and other structural materials

3) plastic boxes and cups: the capacity includes single person consumption and household consumption

VI. dairy packaging development trend

1 Individualization and serialization of dairy packaging

as China is a society with great social, economic and regional differences, dairy packaging is more targeted to its segmented market. Personalized packaging is launched according to the region, consumption habits, tastes, economic ability and age level of the consumer group

dairy marketing is closely combined with dairy packaging

first, low-cost, long-term and easy to transport packaging was launched for the rural market to promote the consumption of dairy products in rural areas

the second is to promote family packaging. Plastic barrels and bottles with a capacity of 0.5 gallons or more will be increased, and family packaging with handles, easy to open and close, and easy to dump will be more popular

third, children's milk packaging should develop more attractive packaging with appropriate packaging capacity and safe drinking, such as polyhedron, stick, cartoon, etc

fourth, the dairy packaging for young people should reflect the characteristics of fashion, uniqueness, vitality and dynamism. Kangmeiduo plastic bag is the packaging of this concept

fifth, the elderly population is increasing. The packaging products should be simple, easy to open and affordable

sixthly, the tourism market continues to flourish, the number of business travelers increases rapidly, and the packaging of dairy drinks should be light, easy to carry, and opened without tools

2. The safety and health requirements for packaging are constantly improving

dairy products are a kind of high time effective products. In the process of processing and packaging, it is necessary to ensure that all microbial indicators of the final products meet the food safety requirements and that the final products are not polluted by chemical substances. Therefore, the safety and health of dairy products is the whole process safety from raw milk production to processing, packaging and consumption

first, the production and transportation of raw milk are safe, creating a reassuring milk source. Raw milk is free of drugs and biological pollution. The aseptic filling technology of box in bag and large bag aseptic filling technology can greatly improve the transportation quality of raw milk

the second is the strict and standardized process control of dairy sterilization and anti-virus, packaging materials sterilization and anti-virus, and the purification level of production environment

the third is the compatibility, migration and transfer of the resin, paperboard as packaging materials and the additives contained in them, the chemical substances and solvents of ink and adhesive after packaging dairy products

fourth, consumers should be convenient and reasonable in the process of secondary storage, unpacking and drinking, and it is not easy to be polluted again. Hangzhou Zhengda color printing factory, which won the gold award of the 18th DuPont global packaging award, "self-contained suction packaging bag", is precisely because its straw is placed on one side of the bag, which has good hygiene, and the special-shaped part of the fixed straw is cleverly designed and convenient to use

3. Green packaging trend

green packaging is the development trend of the whole packaging industry. Dairy packaging is the first requirement due to its wide range of use. Dairy packaging continues to develop in the direction of "4R software, users mainly set relevant safety parameters +1d according to experimental items and requirements", that is, low consumption, low quantity, reuse, recycling and degradability. The greening of dairy packaging should be reflected in the overall greening of the whole process. From raw material manufacturing to recycling, every link should be energy-saving, material saving, efficient and harmless

first, the use of green materials. Polylactic acid, as a fully biodegradable material, has been made into a container in some developed countries, "said Nigel Finney, commercial director of HCs. Aklin packaging is also a kind of environmentally friendly packaging due to its low resin content. The use of new glass bottles is also growing. Use PET material instead of PS material to make cups, and use paper materials for cover films and labels

second, the packaging design should be accurate, without excessive packaging design. The wall thickness of the container is homogenized and thinned, and the design of large capacity packaging barrel relatively reduces the material consumption

thirdly, flexographic printing and water-based ink are used in the production process to eliminate the pollution of chemical solvents

the fourth is the recycling of packaging materials. For aseptic brick packaging with poor environmental protection, three recycling technologies have been developed:

1) hydraulic regenerated pulp technology, which separates Tetra Pak packaged pulp to produce recycled paper, and extrudes the aluminum foil and plastic components into particles to become the raw materials of plastic aluminum products; 2) Plastic wood technology. Tetra Pak contains high-quality paper fiber and plastic, which can be crushed and extruded, and can be directly produced into indoor furniture, outdoor gardening facilities, industrial pallets and other plastic wood products; 3) Color music board technology. Tetra Pak bags are directly crushed and hot pressed to make Caile boards, and then processed into beautiful and durable products such as peel boxes

4. Dairy packaging design if the dairy market promotes the dairy packaging design, the development of dairy packaging design will also promote the development of the dairy market. Dairy packaging design is the core link of dairy packaging, which determines the performance of packaging materials, the structure and shape of packaging, the processing technology of packaging, the color of packaging and the expression of text information

first, the high correlation between dairy packaging and dairy brands makes the differentiated design of dairy packaging very critical. Colors, forms, patterns and words should have strong symbolic characteristics. The emotional appeal is clear and reasonable. The atmosphere is targeted at the target market. Packaging and marketing complement each other, which is conducive to shelf display

second, the design is systematic, taking full account of the protection and quality assurance of packaging materials, the rationality of packaging capacity, the feasibility of packaging and printing box making process, the convenience of bottle caps, straws and other auxiliary elements, the convenience and timeliness of transportation and storage, etc

third, dairy packaging design requires close cooperation between dairy enterprises, packaging machinery and packaging material manufacturers to launch successful packaging
