Product Description
Chocolate bag
The utility model belongs to the field of food packaging bags
The self sealing zipper bag is adopted, and the effect is that when the chocolate in the bag is not finished, the zipper can be sealed for next consumption, which is not only convenient, hygienic, but also environmentally friendly.
Chocolate has brown, light brown, bright and bright appearance, firm and crisp colloidal structure, smooth taste, slightly sweet, high nutritional value, contains protein, fat and sugar, as well as rich minerals such as calcium, iron and phosphorus. It is a food with high calories and is suitable for nutrition and heat supplement for men, women, the elderly and children. However, the quality of chocolate is different, especially the vast majority of chocolate products sold on the market are not cocoa, but cocoa butter. Consumers should know more about the marks on the packaging of chocolate and its products.
In terms of chocolate varieties, in addition to milk chocolate, white chocolate and dark chocolate, there are many flavors of sandwich chocolate.
Milk chocolate: raw materials include cocoa products, powdered sugar, dairy products, spices and surfactants, containing at least 10% cocoa slurry and at least 12% milk.
White chocolate: the ingredients are basically the same as milk chocolate. It includes sugar, cocoa butter, solid milk and spices. It does not contain cocoa powder, so it is white.
Dark chocolate: cocoa paste with sweetener and cocoa butter. Its board hardness is large, its cocoa butter content is high, the average content is 27%, and the milk content is less than 12%.
Nut chocolate: all kinds of whole, half or broken nuts are mixed with pure chocolate in a certain proportion and made into rows, blocks and granules of various specifications and shapes by casting process.
Polished chocolate: there are two main types:
First, take the bulky rice flour products, sugar or nuts as the core, use the rolling hanging garment forming and polishing process on the outside, cover a layer of chocolate, and then polish to make products with very bright surface and different shapes such as round, oblate and oval.
Second, chocolate is used to make cores of different shapes. Sugar syrup is repeatedly hung on the surface of the chocolate core, the surface is covered with a thin layer of sugar coating, and then polished to make sugar coated chocolates of different shapes.
Sandwich chocolate: all kinds of baked products or appropriate candy products, covered with a layer of pure chocolate to form a product with core material sandwiched in the middle of chocolate.
Characteristics of material combination: CPP / OPP --- oxygen proof, oil resistant, moisture-proof, high transparency, good stiffness. CPP / PET: oxygen proof, moisture-proof, fragrance proof and high temperature resistant. PE / OPP --- cold resistant, moisture-proof, low temperature heat sealing, strong tensile force. PE / Pet --- oxygen proof, moisture-proof and fragrance preserving. PE / Al / Pet --- oxygen proof, moisture-proof, high temperature resistance, fragrance retention and chemical resistance. PE / NY --- high temperature resistance, chemical resistance and oil resistance. |
Concept of vacuum packaging: In vacuum packaging, the food is put into the packaging bag, the air in the packaging bag is extracted, and the sealing process is completed after reaching the predetermined vacuum degree. After the air in the packaging bag reaches the predetermined vacuum degree, nitrogen or other mixed gas is filled, and then the sealing process is completed. Principle of vacuum packaging Vacuum packaging refers to the extraction of all the air in the package and the packaging materials with extremely low oxygen permeability, so that the oxygen from the outside can not penetrate into the package, reducing the rate of oxidation and rancidity of fresh meat, so as to ensure the freshness of fresh meat. Fresh meat packed in vacuum can be stored for 14-20 days at 0 ± 1 ºC. After vacuum packaging, the shelf life of the meat will be longer than that of the vacuum packaging. However, if the chilled meat returns to bright red color in the presence of oxygen after removing the packaging, vacuum packaging is generally used in hotels and some hypermarkets that require long storage time and high quality. Materials used in vacuum packaging In addition to polyvinylidene chloride (PVDC) with good oxygen permeability and shrinkage resistance, the materials used for vacuum packaging include polyester, polyamide, or nylon, polyester film and polyethylene multilayer. Polyvinylidene chloride (PVDC) has the highest permeability to prevent oxygen and water vapor, but its biggest disadvantage is that it can't heat seal. Polyester has strong tensile strength and softness; nylon has good oxygen permeability, heat resistance and cold resistance, and strong mechanical properties, but it has high water vapor permeability and high price, so it is mostly used as a vacuum packaging material for fresh meat in the form of multilayer composite. The function of vacuum packaging Inhibit the growth of microorganisms to avoid external pollution; It can slow down the oxidation rate of fat and inhibit the enzyme activity; Reduce water loss and maintain product weight; The package is beautiful, intuitive, and easy to carry. |
