The product is made of non-woven fabric as the raw material, which is a new generation of environmentally friendly materials. It has the characteristics of moisture resistance, breathability, flexibility, lightweight, non combustible, easy to decompose, non-toxic and non irritating, rich colors, low price, and recyclability. This material can decompose naturally after being placed outdoors for 90 days, and has a service life of up to 5 years indoors. When burned, it is non-toxic, odorless, and has no residual substances, thus not polluting the environment.

Advantages of non-woven fabric bags

Environmentally friendly non-woven fabric bags (commonly known as non-woven fabric bags) are a green product that is tough and durable, has a beautiful appearance, good breathability, can be reused, washed, can be screen printed for advertising, has a long service life, and is suitable for any company or industry as an advertising promotion or gift. Economical Starting from the release of the plastic restriction order, plastic bags will gradually withdraw from the packaging market of goods and be replaced by reusable non-woven shopping bags. Compared to plastic bags, non-woven fabric bags are easier to print patterns and have more vivid color expression. In addition, if it can be reused a bit, it can be considered to add more exquisite patterns and advertisements on non-woven shopping bags than plastic bags, because the wear and tear rate is lower than plastic bags, which leads to more cost savings and more obvious advertising benefits for non-woven shopping bags. Having firmness Traditional plastic shopping bags are made of thin and easily damaged materials to save costs. But if we want to make it stronger, it will inevitably cost more. The emergence of non-woven shopping bags has solved all problems. Non woven shopping bags have strong toughness and are not easily worn out. There are also many coated non-woven shopping bags, which not only have durability, but also are waterproof, have a good feel, and have a beautiful appearance. Although the cost of a single bag is slightly higher than that of plastic bags, its service life can be equivalent to hundreds, or even thousands, of plastic bags. Advertising oriented A beautiful non-woven shopping bag is not just a packaging bag for a product. Its exquisite appearance is even more irresistible, and can be transformed into a fashionable and simple shoulder bag, becoming a beautiful scenery on the street.

How to check whether food packaging bags are qualified

How to check whether food packaging bags are qualified

Packaging bags, as we all know, are packaged properly for everything we buy. Do you know if the quality of the packaging bags is qualified? 1. The appearance shall be free from defects such as bubbles, perforations, water marks, blisters, poor plasticization, and fish eye blockages that hinder use. The deviation of specification width, length, and thickness should be within the specified deviation range. 2. The physical and mechanical properties include tensile strength and elongation at break, which reflect the ability of the product to withstand tension during use. If this item is not qualified, food packaging bags (films) are prone to cracking and damage during use. 3. The hygiene performance includes evaporation residue (acetic acid, ethanol, n-hexane), potassium permanganate consumption, heavy metals, and decolorization test. Evaporation residue reflects the possibility of food packaging bags releasing residue and heavy metals when encountering liquids such as vinegar, wine, and oil during use. Residues and heavy metals can have adverse effects on human health, and in addition, residue can directly affect the color, aroma, taste, and other edible qualities of food. 4. The degradation performance can be divided into photodegradation type, biodegradation type, and environmental degradation type based on the degradation type of the product. Degradation performance reflects the ability of a product to be accepted by the environment after being discarded. If the degradation performance is good, the bag (film) will break, differentiate, and degrade on its own under the combined action of light and microorganisms, ultimately becoming debris and accepted by the natural environment; If the biodegradability is poor, it will not be accepted by the environment, resulting in "white pollution".

What are the differences between ordinary packaging bags and food packaging bags

Many people may not know the difference between food packaging bags on the market and other packaging bags, but in fact, there are many differences between the two. Firstly, in terms of raw materials, food packaging bags should be manufactured using food grade plastic films, which are composed of multi-layer composite films, commonly known as hard plastic, transparent or printed. Secondly, in terms of use, food packaging bags should be marked with relevant information, such as the name of the food, ingredients, nutritional composition, implementation standards, shelf life, storage methods, consumption methods, and manufacturer information. Do you know the differences between ordinary packaging bags and food packaging bags? It's okay. Next, let's introduce the difference between ordinary packaging bags and food packaging bags. Let's take a look together. Food packaging safety is a global issue, and the safety standard for food packaging in China is QS, which stands for quality and safety. The dissolution of packaging materials is a key factor affecting food safety and hygiene. As early as 1980, the world-renowned food packaging expert CONORRELY discussed it in his book "METALCONTAMINIONOFFOOD", and in recent years, there have been regulations in the HACCP safety system. 1、 Paper packaging. Paper is the oldest and most traditional packaging material, but its safety hazards cannot be ignored. The main reason is that chemicals such as anti-seepage agents/sizing agents, fillers, bleach, dyeing agents, etc. need to be added to the pulp during the papermaking process. The anti-seepage agent mainly uses rosin soap; The fillers are kaolin, calcium carbonate, titanium dioxide, zinc sulfide, barium sulfate, and magnesium silicate; Bleaching agents include calcium hypochlorite, liquid chlorine, hypochlorous acid, sodium peroxide, and hydrogen peroxide; Dyeing agents use water-soluble dyes and pigments, with the former consisting of acidic dyes, alkaline dyes, and direct dyes, while the latter consists of inorganic and organic pigments. 2、 Plastic packaging, plastic is the most widely used food packaging material. Plastics can generally be divided into two types: thermosetting and thermoplastic. The former includes urea resin UF, phenolic resin PF, and trichlorocyanamide resin MF; The latter includes vinyl chloride resin PVC, polyvinylidene chloride resin PVDC, polyethylene PE, polypropylene PP, polystyrene PS, nylon NY, styrene resin AS, styrene resin ABS, polyester resins such as PET, PEN, etc. Use different additives based on different resins and adhesives used in the production of composite materials, such as TDI, TDA, etc.

Discussion on Packaging Bag Design

To design a good packaging bag, it includes its appearance design, frame design, and color design. Only by including these three aspects can it fully play its role in the design process. Packaging design is not only related to technology and art, but also involves many aspects. Designing a good packaging is not an easy task. The form design alias in packaging design is called form design, which generally refers to the appearance of packaging design. By utilizing the appearance of packaging, it is visually expressed. Packaging design should not only serve the purpose of protecting goods, but also have a good appearance and economic applicability. The framework design of packaging needs to consider its protection, convenience, and reusability, and combine the inside and outside of the packaging according to scientific principles to obtain a suitable design. A good framework design needs to have the function of protecting the product and the convenience of use, and try to make the packaging reusable.
