Rice packaging bags are basically available in every household. In the past, the rice packaging bags used woven bags, that is, snake skin bags. In recent years, we can find that there is a vacuum rice packaging bag. What's the difference between the two? Which one is better?
Rice packed in sacks and sacks can be reused. However, due to its high air permeability, moisture resistance (to prevent mildew and deterioration) and poor light insulation, it is easy to mildew and insect pests. The food plastic bags commonly used in plastic bags are made of polyethylene film, which is non-toxic, so it can be used to hold food. Another kind of film is made of PVC, which is non-toxic. However, according to the use of the film, additives are often harmful to human body and have certain toxicity. Therefore, this kind of film and the plastic bag made of the film are not suitable for food. The following simple method can be used to identify PVC and PE bags:
Vacuum bag is in the extraction of vacuum, and then filled with nitrogen, carbon dioxide and other gases. Nitrogen is an inert gas, which plays a filling role and keeps the vacuum bag under positive pressure, so as to prevent the air outside the bag from entering into the bag, so as to protect the food. Carbon dioxide can inhibit the activity of fungi, spoilage bacteria and other microorganisms. Some foods, such as crispy and fragile food, easy to deform and take oil, with sharp edges or high hardness, will puncture the vacuum bag. After vacuum inflatable packaging, the air pressure inside the vacuum bag is greater than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from crushing and deformation under pressure, and does not affect the appearance of the packaging bag and printing decoration. With the promotion of vacuum bag small packaging and the development of supermarkets, its application scope will be more and more extensive, some will gradually replace hard packaging.
The rice vacuum packaging bag made of high barrier materials such as EVOH, PVDC, PE (polyethylene) t, PA and PE, PP, etc., has the characteristics of moisture-proof (to prevent moldy deterioration of articles), mildew and insects. In addition, the printing pattern and trademark on the rice packaging bag will be obvious, and the text and barcode will be clearly visible, which will attract customers and promote sales. Aluminum foil bag, also known as vacuum packaging, is based on the principle of atmospheric pressure. The main function of vacuum bag is to remove oxygen, so as to prevent food from mildew and deterioration. Vacuum packaging is a process in which the oxygen in the packaging bag and food cells is pumped out by the air extractor, which makes the microorganism lose the "living environment". Vacuum bag can also prevent food oxidation, make food taste unchanged, deterioration, reduce the loss of vitamin A and C. Plastic bags are essential items in people's daily life, and are often used to hold other items. It is widely used because of its low cost, light weight, large capacity and easy storage, but it is forbidden to produce and use in some countries because of its long degradation cycle and difficult treatment. The strength of rice vacuum plastic (structure: synthetic resin, plasticizer, stabilizer, pigment) can be increased by increasing the quality of PE (polyethylene) t and other materials, and its compression resistance and cracking resistance can be improved.
