Plastic water cups may have some information marked on the bottom before leaving the factory. These markings are designed to provide relevant product information, production information and material information. However, these markings may vary depending on the manufacturer, region, regulations, or the intended use of the product.
Here are some of the things that may be marked on the bottom of a plastic water bottle, but not every water bottle will have all the markings:
1. Resin code (recycling identification number):
This is a triangular logo that contains a number that represents the type of plastic used in the cup (e.g. numbers 1 to 7). Some of these plastic types may be considered mandatory labelling, but not all regional regulations require this information to be labeled on water bottles.
2. Manufacturer information:
Including manufacturer, brand, company name, trademark, production location, contact information, etc. Some countries may require this information to be included.
3. Product model or batch number:
Used to trace production batches or specific models of products.
4. Food grade safety label:
If the water bottle is used for food or beverage packaging, it may need to include a specific food grade safety mark to indicate that the plastic material meets food contact safety standards.
5. Capacity information:
The capacity or volume of a water glass, usually measured in milliliters (ml) or ounces (oz).
6. Environmental protection or recycling signs:
Indicate the environmentally friendly nature or recyclability of the product, such as a “recyclable” mark or environmental symbol.
In some cases, specific marking may be necessary, such as a food grade safety mark, to ensure that plastic materials meet food safety standards. However, not all national or regional regulations require all of this information to be marked on the bottom of plastic water cups. Producers and manufacturers sometimes use their own policies and industry standards to determine what information to label on their products.
