Many users have a habit of reusing containers of food but did not know about the symbols at the bottom of plastic containers may allow re-use or not.

Currently, there are many types of plastic packaging mainly high-molecular chemistry (polymer).

Codes are numbered from 1 to 7 and surrounds the figure denotes the triangle with arrows, i.e. there is a specific figure inside the triangle, the bottom of the triangle is the acronym as PETE, PP PS … We need to rely on symbols under boxes / plastic bottles for properties as well as the scope of use, whether to reuse or not to health is not affected. The code is as follows:

Code 1: polyethylene terephthalate (PETE or PET).

Code 2: High-density polyethylene (HDPE).

Code 3: Polyvinyl chloride (PVC), also called vinyl (V).

Code 4: Low-density polyethylene (LDPE).

Code 5: Polypropylene (PP).

Code 6: Polystyrene (PS).

Code 7: Polycarbonate (PC) or others.

In the above types of plastics, code 1 (PET or PETE), code 2 (HDPE) and code 5 (PP) are used for packaging in contact with food.

However, PET or PETE plastic usually be made of bottles of water and soft drinks bottling quality assurance only for one-time use, that means not reusable.

Code 2 (HDPE) and code 5 (PP) are the best choices for food packaging: Code 2 (HDPE) is hard plastic used to manufacture milk bottles, cooking oil bottles, including toys and some plastic bags can be reused; code 5 (PP) is also suitable manufacturing food containers, and plastic food covers. They are safe for people to recycle or reuse.

You can rest assured when the water bottle, your belongings have symbol of code number 2 (HDPE) and number 5 (PP).
And code 6 (PS) is also made of foam containers such as plastic bag, drinking glasses, foam coffee cup or food foam containers used only once, that is not reused.

Code 3 (PVC) or 3V, as well as number 7 (PC) is the worst kind, with the advice to stay away from them because they may contain very toxic additives.

You should not process food overheating or use the bowls and plastic packaging in the microwave in which should be replaced by containers made of glass, porcelain.

Maybe replace the bottles, plastic jars with glass bottles to contain fish sauce, cooking oil or water food.

Do not let children play plastic toys when the child is sucking or sucking toys to mouth. You can use paper packaging instead of plastic packaging, plastic is better – in terms of environment and health protection.
