Food packaging materials refer to products used for packaging, holding food or food additives and coatings that are in direct contact with food or food additives. It can be seen that the quality of food packaging materials directly affects food safety.
Food plastic packaging materials: Plastics are the most widely used food packaging materials. The unsafe hidden danger lies in the migration of monomers, formaldehyde, toluene and other compounds in the resin. In addition, the use of additives added to the manufacturing process, such as stabilizers, colorants, plasticizers, etc., causes certain compounds to migrate into the food, affecting food safety.
Food paper packaging materials: Paper is the oldest and most traditional packaging material. In the papermaking process, chemicals such as impermeable agents, bleaching agents, dyeants, etc. are added to the pulp, and some chemicals will migrate into the food. From paper products, mold inhibitors or formaldehyde used in processing can also be dissolved.
Food metal packaging materials: metal packaging mostly uses aluminum foil, iron foil and tin-plated cans. When using aluminum foil, it is rarely used alone, and is mostly used with plastic film bonded. Most of the surface of the metal cans is coated with plastic. Therefore, some compounds in heavy metals and additives migrate into food, affecting food safety.
Food glass container packaging material: glass is also a melt of inorganic substances, and its main component is SiO2-Na2O. Because of the different types of glass, there are extractables from the raw materials.
In addition, the coloring of food packaging materials requires the use of metal salts, and if heavy metals migrate into food, it will also affect food safety and pose unsafe hidden dangers.

Anti-Static Shielding Bag

The room with anti-static flooring should maintain the necessary temperature and temperature. Generally, the temperature should be less than 28 ℃, and it is better to maintain the temperature between 50% and 70%, but not suitable for less than 40%. That kind of temperature can keep the wooden floor relatively stable. If the ecological temperature cannot reach it, a humidifier can be used to increase humidity. If there is a large amount of water immersion or partial water bubbles accidentally, there must be water lingering. It should be immediately absorbed with a damp cloth and the floor tile ecology should be dry. Do not use an electric heater to air dry or expose it to the sun.
