We all know how important it is for you to reduce, recycle and reuse. In order to reduce our dependence on plastics, we repeatedly use them. But is that even safe? Is a China blow molding machine even safe for making recycled (polyethylene terephthalate) PET bottles?
Let’s see here …
What ingredients is the plastic bottle made of?
In this section we will give you an idea of what plastic bottles are made of. While we all think plastic bottles are made of PET, the reality is very different. Plastic bottles are made of synthetic polymers that contain various organic compounds, mostly carbon compounds.
Each type of compound from which the bottle is made has to be separated separately and then reused in the recycling process.
While you may have heard of polyethylene terephthalate, it’s not the only compound used in the manufacture of plastic bottles.
Some of the other compounds that a China blow molding machine uses in making plastic bottles include high density polyethylene, PVC or polyvinyl chloride, low density polyethylene or LDPE, polypropylene, polystyrene or PS and some other compounds used very little.
Problems with reusing PET bottles
We’ll start with a discussion of how safe it is to reuse your plastic bottles by starting with the PET bottles, which are the most common ingredient in the manufacture of plastic bottles.
The problem, however, is that while it doesn’t contain compounds like BPA, it does contain some other compounds aldehyde and antimony in small amounts. The problem is, antimony will leak out of the bottle itself when exposed to a slightly high temperature. For example, if you keep the PET bottle in an open place in the hot summers where it can be exposed to direct sunlight, or if the bottle is kept in contact with an engine of your car, for example.
In general, you will find that manufacturers state that the PET bottles are for single use only. Even the FDA, one of the most famous medical and health agencies in the world, has recommended that PET bottles be used only once and then only reused if it is safe and indicated by the manufacturer.
Problem with HDPE or high density polyethylene
Compared to the PET compound, HDPE does not have a high risk of leaching. HDPE contains non-polyphenols that have been shown to be harmful to aquatic organisms.
In addition, doctors and health experts suggest that it can also cause problems with the endocrine system in our bodies. The endocrine system is an essential system that mainly controls the number of hormones that are secreted by the glands.
However, using HDPE bottles has an advantage that bacterial growth can be easily prevented.
The China blow molding machine uses the HDPE compound to make larger bottles, milk jugs, and gallon liter water bottles. You can also recycle them with high efficiency.
There are some other plastics, polycarbonate plastics, epoxy raisins that are also used to make PET bottles. These contain a harmful substance, BPA or bisphenol A, which is a notoriously dangerous substance and can leak into the liquid it contains. BPA can cause serious problems to your endocrine system and it can also lead to several health problems, including male infertility, prostate cancer, breast cancer, and early puberty. It can have serious effects on the heart and brain, especially in the younger population.
Is It Safe For You To Reuse Plastic Bottles?
Indeed, some plastic bottles are safe to reuse, but you cannot use them over and over for several years.
The most important thing for you is to understand the manufacturer’s certifications and what the manufacturer tells you to do with the reusable part.
And while you know, the certifications from the PET bottle retailer also confirm this. You need to be proactive to keep yourself and your family healthy and also to make sure that you only use the plastic bottles for a short time. While they are safe to use, ideally they shouldn’t be used for several years, say more than 3 or 4 years at a time.
At least you don’t have to keep buying new bottles.
Choose the environmentally friendly alternative
There are certainly interesting variants of the PET bottles produced by a China blow molding machine. From a health point of view, too, you can find the best varieties in many shapes and sizes. However, choosing a healthier alternative like using bamboo, aluminum, or copper bottles is a better choice, although it can be a slightly expensive option.
