[China Packaging Network News] When it comes to packaging whole grains, vacuum sealing is highly recommended. This method significantly extends the shelf life of the product by preventing oxidation and odor absorption, which in turn helps to reduce the risk of mold growth. Vacuum packaging is especially beneficial for preserving the freshness and quality of grains over a longer period.
For high-fat foods like pre-cooked meals found in supermarkets, it's important to avoid using plastic bags for more than two hours. Grease from these foods can act as a solvent, causing chemicals from the plastic to leach into the food. Typically, the highest level of chemical migration occurs after about two hours of contact between oily food and plastic packaging.
When using plastic cup lids for hot beverages such as tea or coffee, it’s advisable not to cover the lid immediately after pouring boiling water. The heat resistance of most plastic lids is limited to around 90°C. Exceeding this temperature may cause the lid to warp or even release harmful substances, which could potentially contaminate the drink.
When purchasing plastic bags for items like pastries or noodles at supermarkets, always choose those labeled as "food-grade" and featuring the "QS" certification mark. Additionally, check that the bag is transparent, smooth to the touch, and free of any strong odors, as these are signs of better quality and safety.
It's also important to note that plastic-wrapped foods should not be heated in a microwave oven. Most supermarket packaging uses high-density polyethylene (HDPE), which is generally safe and non-toxic. However, when exposed to high temperatures, some plastics may release harmful substances into the food, making it unsafe for consumption. Always follow the manufacturer's guidelines for safe use and disposal.
