Mga benepisyo ng aluminyo foil para sa industriya ng pagkain

Ang aluminyo foil ay gawa sa pangunahing aluminyo haluang metal at gumulong sa pamamagitan ng maraming mga proseso. Wala itong mga mapanganib na sangkap tulad ng mabibigat na metal. Sa proseso ng produksyon ng aluminyo foil, ang mataas na temperatura annealing proseso ay pinagtibay. Samakatuwid, aluminyo foil ay maaaring madaling makipag ugnay sa pagkain at hindi maglalaman o mag ambag sa paglago ng bakterya. Sa karamihan ng mga kaso, aluminum foil will not react with food. A considerable number of plastic lunch boxes in the market are produced from unknown raw materials or even fake materials and waste plastics, so the quality and reliability are difficult to guarantee. If calcium carbonate, talc powder, industrial paraffin and recycled waste are added to the production raw materials of disposable plastic tableware, the evaporation residue (n-hexane) of the product is easy to exceed the standard. In order to protect the environment and prevent the harm of plasticizers to society and human body, the government has also formulated laws and regulations to restrict the use of disposable non degradable plastic tableware.

aluminum foil packaging pagkain

Aluminum foil has high conductivity, which can greatly reduce the time and energy related to food processing, refrigeration and secondary heating. Aluminum foil has good thermal stability. In the process of processing and packaging, aluminum foil utensils can well withstand the change of temperature. Under the high and low temperature of - 20 ° C-250 ° C, the molecular structure is stable. Its service temperature can range from rapid freezing to extreme baking and barbecue. During this period, the aluminum foil will not deform, crack, melt or scorch, and will not produce harmful substances. Aluminum foil is used to separate high-temperature charcoal fire and smoke, which can avoid carcinogens caused by food scorching. Aluminum foil lunch boxes and containers are very suitable for high temperature... And heat sealing treatment. Aluminum foil lunch boxes and containers can be heated in a variety of ways, including various ovens, ovens, anaerobic heating cabinets, steamers, steamers, microwave ovens (always use in light wave and barbecue stalls) and pressure cookers to heat with aluminum foil pagkain packaged. Relevant enterprises have developed supporting aluminum foil lunch box secondary heating equipment and packaging equipment, which can greatly improve the distribution efficiency of catering enterprises and the quality of meals. Sa kabilang banda, the high temperature resistance of plastic lunch boxes and containers is significantly lower than that of aluminum foil products. They will release harmful substances after contacting high-temperature food, water or heating at high temperature, affecting human health( The foamed lunch box is made of polystyrene. The softening point of polystyrene raw material is 87 °C - 97 °C. Samakatuwid, it cannot be used in a temperature environment above 80 °C.
