Black pet food bags belong to plastic handbags, which are usually divided into four types: bottom edge, bottom edge, bottomless and boundless. After considering beauty and practicality, the vast majority of customers choose the side style, one reason is that the side style is more three-dimensional and more beautiful, the bag can stand and will not fall on the ground, and the side can also be printed with pattern, LOGO or QR code, which increases the chances of others' attention. Although the black pet food bag is a plastic bag, this style close to the paper bag requires three manual processes, so it is much more expensive than other styles, so many people use the style with no side at the bottom in order to save costs.

In the packaging industry, PE bag usually refers to the bag made of LDPE material. PE material is widely used and is used in many bags with different functions. Polyethylene is insoluble in water and its water absorption is relatively small, that is, some chemical organic solvents, such as toluene and acetic acid, will dissolve slightly when the temperature is higher than 70 ℃. However, polyethylene in granular form can also be melted or cured with the change of temperature between 15 ℃ and 40 ℃.

However, many friends often have misunderstandings when buying and using food packaging. Today, packaging will teach us how to get out of the misunderstanding and choose and use food bags correctly. 1. Three major misunderstandings in the purchase and use of food bags. I like to buy food bags with bright colors. Food bags have a wide variety of colors, and many friends are easily attracted by brightly colored products when they buy, but the brighter the color of food packaging, the more additives there will be, so it is recommended to use monochromatic bags for food packaging. Although the decoration has declined, after all, contact is the entrance to things, and safety is the most important. I like to collect old food bags and reuse them. Many friends, especially the elderly, are used to storing old food bags in order to save resources. This common practice is actually very unhealthy and undesirable. The thicker the food bag, the better. The thicker the food bag, the better the quality. In fact, there are strict standards for packaging bags, especially food bags, and the quality that meets the standards is qualified and has nothing to do with the thickness. Second, how to choose food bags correctlyA. Do not choose and buy food with fuzzy printing in outer packaging; secondly, if you use hand rubbing to print transparent bags, if you find that they are easy to decolorize, it means that their quality and material are not good, there are unsafe factors, and you can't buy them. two。. Sense of smell. Don't buy food bags that are irritating and spicy. 3. Pack food in white plastic bags. Although it is recommended to use other environmentally friendly packaging instead of plastic, it is recommended that you try not to use red and black plastic bags when you need to use them. Because colored plastic bags may use recycled materials, or unpurified natural materials and their rough processed products, they can easily fail, deteriorate, mildew or be contaminated, thus contaminating food. Pay attention to food-grade paper packaging. Paper packaging is the development trend of packaging in the future. Recycled paper, like colored plastic, is not suitable for food. Ordinary paper materials due to some reasons will add additives, so the purchase of food paper packaging must pay attention to food grade. How can "safety on the tip of the tongue" be careless? For our health, please buy food bags produced by regular manufacturers and approved by the relevant departments. At present, all kinds of food bags emerge in endlessly in the market, especially food bags. For ordinary people, they may not quite understand why there are so many kinds of food bags. In fact, in the packaging industry, they also have names according to the type of bags. Today, this article lists the most common food bags in life. Let you know, eat with peace of mind! The first kind: three-sided sealed bag. As the name implies, that is, three-sided sealing, leaving an opening to accommodate the product, is the most common type of food bag. The three-sided sealing bag has two side seams and one top seam, which can be folded or unfolded. When there is a hem, please stand upright on the shelf. The second kind: self-help bag. The self-contained food bag is as easy to understand as its name. It can stand on its own or on a container. Therefore, the display effect is better and more beautiful. The third kind: octagonal sealing bag, which is developed on the basis of self-supporting bag, because the bottom is square, so it can also stand upright. This kind of bag is more three-dimensional, with three planes: front, side and bottom. Octagonal sealed bags have more printing space than independent bags.
