How to Use PET Transparent Plastic Bottle Correctly

There are usually two ways to identify the melting point of PET transparent plastic bottles. One is to use the melting point tester, which can easily test whether it is normal or not. The other is to ignite and burn the raw materials and pull the wires off after lengthening. If the broken wires can be rolled into several rolls, this means the melting point is normal. If the raw materials melt quickly after ignition, the melting point of the raw materials is low. If the bottle pieces become very black after burning, it also means that the melting point is low; and if the taste smells particularly sweet, it also means that the melting point is low.

Smell the smell. PET tastes different from ordinary plastics. If you burn it with a lighter, you will smell a very fragrant and comfortable smell.

If PET contains some other ingredients, its taste will be very pungent. Usually this kind of bottle contains SEBS ingredients, * do not choose.

When burning, pull the silk on the lighter to see if the silk is long, then pull the pulled silk off and see if the middle breakpoint is rolled into a small circle. The more it is rolled, the higher the melting point. Under normal circumstances, if it is a bottle tablet, there should be no big problem. * It is important to distinguish whether it contains PVC components, which are absolutely not allowed in PET.

It seems that the burning part, if it is too black or the oil drops quickly, is the melting point is abnormal, which should be paid attention to in the plastic bottle film.

After the PET transparent plastic bottle is opened, bacteria and fungi will breed in the humid or liquid-containing environment in the bottle. If the bottle is re-filled, the newly injected water will be contaminated.. These microorganisms generally come from the air, human hands or mouth, or anything that touches the mouth of a bottle. In a warm environment, bacteria can multiply to harmful levels over time. However, safe handling and proper cleaning can prevent bacteria from growing.

Chemicals used to make bottles (such as chemical monomers and additives) may migrate from the bottle to the water or beverage in the bottle, regardless of whether these bottles have been used once or multiple times. If you want to buy Henan transparent plastic cans, please consult Henan transparent plastic bottle manufacturer Kaifeng packaging, a professional Henan pet packaging bottle manufacturer. The chemical migration of plastics is affected by many factors, including the characteristics of the substances in contact with plastics, the temperature and time of contact. If plastic is used correctly, the amount of chemical migration will only be negligible and will not pose a risk to the health of consumers.

PET transparent plastic bottles contain trace amounts of antimony. Antimony is a heavy metal used to make transparent plastic bottles. During the storage of water, the antimony contained in transparent plastic bottles can migrate into the water. However, past research by the Center for Food Safety has shown that PET transparent plastic bottled beverages have very low antimony content (far below the World Health Organization's guidelines for water quality) and do not pose a health risk. Regardless of the type of plastic, chemical migration will increase with the temperature and contact time of the plastic. Although the migration of more chemicals from transparent plastic bottles does not necessarily pose a health risk, it may change the sensory characteristics such as the color, aroma and other sensory characteristics of the water in the bottle, so it is not appropriate to allow transparent plastic bottled water to be directly exposed to sunlight.
