While officials and waste-reduction activists have urged customers to bring their containers to their favorite food trucks, many individuals still choose to use the disposable options offered by the vendors.
1. What Is In My Container?
Leung said disposable plastic food containers are often constructed of plastic resins blended with additives. Additives are chemicals that can enhance the plastic's properties, such as making it more flexible or giving it a better finish. The senior lecturer and expert at Nanyang Polytechnic's School of Applied Science elaborated, "Some of these chemicals are included in the disposable box is meant to handle high-temperature meals."
2. Which Kind of Plastic is Safest?
Foods that need to be kept hot or that will be microwaved require special containers. Leung emphasized the importance of consumers selecting the appropriate plastic for their needs, even when purchasing reusable containers. He said that a heat-resistant, reusable plastic container is something to consider if your container is going to be heated regularly. Because of its high heat resistance, polypropylene, for instance, is the best material for use in microwaves. High-density polyethylene containers are ideal for the fridge and freezer.
3. Are Disposable Containers Safe For Hot Soup?
Leung warned that putting hot soup in a plastic container that was not designed to withstand such high temperatures is dangerous. The label on microwave-safe containers will indicate as much, but it may also tell the user to remove the lid first.
4. May I Refuse Disposable Containers?
It would help if you only used them once. As stated on their website, Leung stressed the significance of a "like-for-like" strategy if one must recycle throwaway plastics. It amounts to substituting water for coffee while reusing a bottle of water. He also cautions his associates to be on the lookout for warning indications indicating they ought to abandon using a container. Seeing discoloration suggests it became too hot in one spot. The texture of the takeout container could grow firmer or softer with continued usage. According to Leung, "these are evidence that it has gone past the limitations of the plastic compositions."
5. Reusable and Disposable Containers Are Polypropylene?
The plastic used to make reusable containers is designed to "resist specific physical cleaning." As a result, even if the containers' labels all have the same code, the plastic used to make the containers may be significantly different. The manufacturer could have made it more resistant to oil and acid. The disposable (container) design only has room for a couple of additional features.
6. What Rules Apply To Food Containers?
In Singapore, the importation, sale, and usage of goods that come into touch with food are all regulated under the Sale of Food Act. It is not acceptable for food containers to be able to transmit lead, antimony, arsenic, cadmium, or any other potentially dangerous chemical to any food that is stored, prepared or cooked in them (NIH). There is no possibility of obtaining pre-market authorization from the SFA for food packaging.
