Yes, chewing gum often contains plastic.
Many commercially available chewing gums include a synthetic rubber base that is essentially a type of plastic. Specifically, polyvinyl acetate (PVA) is a common ingredient in gum base.
The Role of Plastic in Chewing Gum
- Gum Base: The "gum base" provides the chewiness and elasticity of the gum. This base typically consists of a blend of synthetic rubbers, resins, and waxes, including plastics like PVA.
- Polyvinyl Acetate (PVA): This plastic polymer is used to provide the gum with its texture and ability to hold its shape during chewing. It's also used in the production of glue, plastic bags, and bottles.
Concerns About Plastic in Gum
- Environmental Impact: Since many gums contain non-biodegradable plastics, discarding used gum can contribute to plastic pollution. It persists in the environment for extended periods.
- Health Considerations: Although PVA is considered safe for consumption in small quantities by regulatory bodies like the FDA, some consumers are concerned about ingesting plastic.
Alternatives to Plastic-Based Gums
- Natural Gum Bases: Some companies are exploring and producing gums with natural gum bases, often derived from tree saps like chicle. These gums are biodegradable and offer a more sustainable alternative.
In summary, while not all chewing gum is entirely plastic, a significant portion of commercially available gums utilizes plastic polymers like polyvinyl acetate as a key component of the gum base.
