Disposable tableware is usually produced using the following materials:
1. Plastics
- Polypropylene (PP): good heat resistance, commonly used in the production of disposable lunch boxes, cups and bowls.
- Polystyrene (PS): commonly used in the production of disposable cups, plates and cutlery, high transparency, but poor heat resistance.
- Polyethylene (PE): commonly used to make disposable plastic bags and films.
2. Paper
- Paperboard: commonly used to make disposable cups, lunch boxes and plates, usually coated with a layer of polyethylene (PE) or polylactic acid (PLA) to enhance water and oil resistance.
- Bagasse paper: Made from bagasse, it is environmentally friendly and biodegradable, and is commonly used to make disposable lunch boxes and plates.
3. Biodegradable materials
- Polylactic acid (PLA): made from renewable resources such as corn starch, biodegradable and commonly used to make disposable tableware and cups.
- Starch-based materials: made from corn, potato and other plant starches, biodegradable, commonly used to make disposable tableware.
4. aluminium foil
- Aluminium foil: commonly used for making disposable lunch boxes and containers, with good heat insulation and freshness preservation properties.
5. wood
- Wood chips: commonly used for making disposable chopsticks, forks and spoons, which are environmentally friendly and biodegradable.
- Bamboo: commonly used for making disposable chopsticks, bowls and plates, environmentally friendly and biodegradable.
6. Other materials
- Plant fibre: such as wheat straw, rice husk, etc., commonly used in the production of disposable lunch boxes and plates, environmentally friendly and biodegradable.
- Edible materials: such as seaweed, starch, etc., which are under research and development and may be used to make disposable tableware in the future.
Production process
1. Preparation of raw materials: select suitable materials and carry out pre-treatment.
2. Forming: Process the material into the desired shape of tableware by injection moulding, compression moulding, hot pressing and other processes.
3. Post-processing: Cutting, trimming and polishing are carried out to ensure the appearance and quality of the products.
4. Inspection and Packaging: Conduct quality inspection and package after passing the test.
Environmental Consideration
- Biodegradable materials: Use biodegradable materials to reduce the impact on the environment.
- Recycling: Establish a recycling system to recycle and reuse disposable tableware.
With the above materials and processes, disposable tableware is able to meet the needs of different scenarios, and at the same time, it is constantly developing in the direction of environmental protection and sustainability.
