Do not use this plastic bag as a food bag!

There are two kinds of plastic bags (structure: synthetic resin, plasticizer, stabilizer, pigment) that are common in the market, one is a new plastic bag, and the other is a recycled plastic bag. The difference between them is the raw material. Different, the former is made of new polyethylene plastic granules, which are characterized by smooth and soft products, colorless, odorless and non-toxic, and are generally used in food packaging bags; the latter is recycled plastic waste or waste, which has been screened and processed. It is made of plastic granules, which are characterized by insufficient color, colorful and rough surface. This product is generally used for industrial and agricultural or ordinary life product packaging due to the messy source of raw materials and a certain degree of toxicity. At present, the Ministry of Health has issued a notice to The production and use of recycled plastic bags are strictly regulated, and it is forbidden to be used in any food packaging products, because it contains toxicity and has a great impact on people’s health. The vacuum bag is filled with nitrogen, carbon dioxide and other gases after the vacuum is drawn. Nitrogen is an inert gas, which acts as a filling and keeps the vacuum bag at a positive pressure to prevent the air outside the bag from entering the bag, and has a protective effect on the food. Carbon dioxide has the activity of inhibiting microorganisms such as mold and spoilage bacteria. Some foods such as crispy and fragile food, easily deformed and oily food, food with sharp edges and corners or high hardness will puncture the vacuum bag, etc. After vacuum inflatable packaging, the inflation pressure in the vacuum bag is stronger than the atmospheric pressure outside the packaging bag, which can effectively Prevent the food from being crushed and deformed under pressure, and does not affect the appearance and printing decoration of the packaging bag. With the promotion of vacuum bag small packaging and the development of supermarkets, its scope of application will become more and more extensive, and some will gradually replace hard packaging. Plastic bags are an indispensable item in people’s daily life and are often used to hold other items. It is widely used because of its advantages of low cost, extremely light weight, large capacity, and easy storage. However, due to the shortcomings of extremely long degradation cycle and difficult disposal of plastic bags, it has been banned by some countries for production and use. Black, red, blue and other dark-colored plastic bags currently used on the market are mostly reprocessed from recycled waste plastic products and cannot contain food. Ultra-thin plastic bags (thickness below 0.025 mm) are also prohibited from containing food. Aluminum foil bags are generally stored away from direct sunlight and stored away from fire sources. They can be stored for 2 years at room temperature of 25 degrees Celsius. Aluminum foil bags are also called polyamide 66 or nylon 66. Yellowish translucent or milky white opaque resin. The relative density is 1.14~1.15, and the melting point is 259~267℃. It has excellent wear resistance, oil resistance and self-lubricating properties, and is the highest variety in aliphatic nylon in terms of heat resistance, strength and rigidity. Tensile strength 75.9~82.9MPa, compressive strength 91MPa, Izod impact strength (notch) 4kJ/m, thermal deformation temperature (1.82MPa) 75℃, hardness R120, volume resistivity 1015Ω·cm, dielectric strength 35kV/mm, self-extinguishing. By adipic acid and hexamethylene diamine polycondensation obtained. It can be processed by extrusion, injection molding, blow molding and other methods. It can be reinforced, filled, and alloyed for modification. It is widely used as fiber and tire curtain vacuum bag packaging material, which is usually a three-sealed packaging bag made of double-layer composite film or three-layer aluminum thin composite film. Two types of vacuum packaging machines are commonly used: cavity type and external pumping type. China’s vacuum packaging technology was developed in the early 1980s, and vacuum inflatable packaging technology began to be used in the early 1990s. The vast majority of these recycled plastic bags are produced by small companies or family workshops, and a considerable number are recycled and processed using collected waste plastics, industrial wastes and plastic wastes discarded by medical institutions. Bacteria and carcinogens, the use of such plastic products to package cooked food directly into the mouth will have extremely serious consequences on the health of consumers.
