In the production of composite plastic flexible packaging, in addition to colorful printing plastic bags, there is another kind of plastic bags that are not printed. It should be pointed out that white, black or other pure color plastic bags, although there is no pattern and text on the surface of this plastic bag, but this solid color plastic bag is also a printed plastic bag, and it is also necessary to make plates when making this kind of plastic packaging. Another non-printing plastic bag is a transparent plastic bag, mostly vacuum bags, which maintain the original color of the plastic film without plate making. So, what are the uses of transparent vacuum plastic bags?
Clear vacuum plastic bags are a widely used form of packaging that extends the shelf life of food and other products by extracting air from the bag and sealing it, creating an oxygen-free environment. Such bags are usually made of multiple layers of composite materials, including polyethylene (PE), polypropylene (PP), nylon (PA) or other high barrier materials to ensure their transparency and sealing properties.
Transparent vacuum plastic packaging has good performance, these characteristics make transparent vacuum bags become the ideal packaging choice for food, medical, industrial products and other fields.
Preservation: can effectively remove air from the inside of the package, slow down the oxidation of food, mildew and bacterial growth.
Transparency: allows consumers to directly see the product inside the package, increasing the integrity and attractiveness of the product, and increasing the desire to buy.
Sealing: Good sealing performance can prevent external pollution, and maintain the original taste and quality of the product.
Protective: Provides a certain degree of protection to reduce physical damage during transportation and storage.
Extended shelf life: A vacuum environment can significantly extend product shelf life and reduce waste.
Space saving: Vacuum packaging will reduce the volume of the product, easy to store and transport.
Environmental adaptability: Transparent vacuum bags can maintain performance in a certain temperature range, suitable for freezing or refrigerating products.
According to the characteristics of the vacuum transparent plastic bag, it can play a role in a variety of scenarios.
1. Vacuum transparent plastic packaging bag is very suitable for use as the inner bag of product packaging. The most common rice packaging bag, now many rice packaging in order to be beautiful and convenient to use, will be customized two layers of plastic packaging bags, the outer layer is printed with a beautiful pattern of plastic packaging bags, the inner layer with ordinary transparent vacuum plastic bags to package rice, increase the packaging maturity, not only improve the product packaging grade, make the product more beautiful, At the same time, the transparent vacuum plastic bag in the inner layer will strengthen the packaging protection of the product, and the transparent sense of transparency also makes consumers open the bag at the first glance to see the appearance of the product.
2. Transparent vacuum plastic bags are suitable for products that need to display the appearance of products. Some companies in order to show their confidence in their products, but also in order to show their goods in a more comprehensive way, so that their products at a glance, increase the appeal of consumers, will also use transparent vacuum plastic bags to package products. This kind of transparent vacuum plastic bag used alone generally prints some text information, trademarks, selling points and contact information in a small area, but retains a large area of transparent color, which is the biggest feature of this transparent vacuum plastic bag.
3. A small amount of household food storage is suitable for using transparent vacuum plastic bags. Sometimes we need to save a small amount of food, daily necessities, etc., at this time many people will choose to buy transparent vacuum plastic bags for packaging, so that one is because such transparent vacuum plastic bags are very convenient to buy, various models are relatively complete, and the other is because the transparent bags are very suitable for observing the preservation of food in the packaging.
In specific applications, vacuum transparent plastic packaging and food, agriculture, medical, electronics and other industries are very high fit, and therefore widely used.
