Kraft paper is used in the chemical, mechanical and other industries, especially in food packaging.

1.Kraft paper is widely used in a variety of packaging supplies, paper bags, handbag kraft paper, color boxes, gift boxes kraft paper, printing kraft paper, notebook kraft paper, workbook kraft paper, kraft paper for envelopes, food packaging, a variety of high-end commodity packaging; gift boxes such as wine boxes, sportswear, etc.; envelopes such as literature, education and health, enterprises and institutions to preserve the archives. Such as common postal seals; can also be processed shopping bags, such as shopping malls and brand stores commonly used in shopping bags or for the inside of the paper, etc. Kraft paper's anti-stretch advantage makes it perfect for packaging needs, thus avoiding the drawback of bags being pulled off.

2.Kraft paper can also be used as a cushioning material. Some precision parts such as car parts need cushioning. Kraft paper is a very good cushioning material. Cut it into thin strips and fill it with it to play the role of cushioning, both environmentally friendly and cheap.

3.Kraft paper is especially suitable for making multi-layer kraft paper bags for cement, putty powder, barite powder, titanium dioxide, dry mortar and other powdered products, as well as insulating paper, asphalt paper, cable protection paper, adhesive sealing paper and so on. It is moisture-proof, leak-proof, easy to stack, not easy to slip, safe to transport, etc. It is one of the most chosen packaging materials at home and abroad! The advantage of packaging with kraft paper is determined by the performance of kraft paper, because kraft paper can be recycled and reused many times, recycling, environmental protection, and the price is not high, low printing costs, cost savings.

4.In order to prevent consumers from taking out food when the bag is pulled off, packaging materials are required to have good tensile strength. Beverage packaging requires materials with a certain degree of moisture resistance and non-deformation ability to prevent water absorption deformation and damage. For the packaging of frozen food, the use of high-strength materials as packaging is also an important consideration. This material must be able to withstand the thermal expansion and contraction of low-temperature freezing and high-temperature thawing, and prevent deformation, distortion, wrinkling and excessive moisture absorption. Conditions of packaged foods. In these respects, primary color kraft paper is even more suitable than SBS paper.

Only biodegradable plastics can fundamentally solve the problem of white pollution.kraft food box wholesale Degradable plastics and recycled plastics are two potential options for solving the white pollution problem. Degradable plastics refer to plastics whose product properties can meet the requirements of use performance, remain unchanged during the storage period,cornstarch bags and can be degraded into environmentally sound substances under natural environmental conditions after use.

Degradable plastics can be classified by different degradation methods or different raw materials.double paper coffee cups wholesale According to the classification of degradation methods, degradable plastics can be divided into four categories: biodegradable plastics, light-degradable plastics, light and biodegradable plastics, and water-degradable plastics. At present, the technologies for photodegradable plastics and photo- and biodegradable plastics are still immature, and there are few products on the market. Therefore, the degradable plastics mentioned hereafter are all biodegradable plastics and water-degradable plastics.According to the classification of raw materials, degradable plastics can be divided into bio-based degradable plastics and petroleum-based degradable plastics. Biodegradable plastics are plastics produced with biomass as raw materials, which can reduce the consumption of traditional energy sources such as petroleum, mainly including PLA (polylactic acid), PHA (polyhydroxyalkanoate), PGA (polyglutamic acid), etc.Petroleum-based degradable plastics are plastics produced from fossil energy sources. They mainly include PBS (polybutylene succinate), PBAT (polybutylene adipate/terephthalate), and PCL (polybutylene terephthalate). Ester) and so on.

Degradable plastics have their advantages in performance, practicability, degradability, and safety. In terms of performance, biodegradable plastics can reach or exceed the performance of traditional plastics in certain specific areas; in terms of practicality, biodegradable plastics have similar application performance and hygienic performance to similar traditional plastics; in terms of degradability, biodegradable plastics After use, it can be degraded quickly in the natural environment (specific microorganisms, temperature, humidity), and become fragments or non-toxic gases that are easily used by the environment, reducing the impact on the environment; in terms of safety, degradable plastics are degraded The substances produced or remaining in the process are harmless to the environment and will not affect the survival of humans and other organisms. At present, the biggest obstacle to replacing traditional plastics is also the disadvantage of biodegradable plastics in that their production costs are higher than similar traditional plastics or recycled plastics.10 inch pizza box Therefore, in applications such as packaging, agricultural film, etc.,which have a short use time, are difficult to recycle and separate, have low performance requirements, and have high impurity content requirements, degradable plastics have an alternative advantage.
