Plastic or polymer is one of the most valuable components that hasenormous popularity in the 21st century. Due to its lightweight and cost-effective nature, the popularity of plastic is growing rapidly. Humans cannot imagine a day without the usage of plastic. Some polymers may create serious health hazards for humans. Thus, it is essential to use good quality plastic for commercial usages.
What is PET Plastic?
PET plastic or polyethylene terephthalate is a general-purpose using thermoplastic-polymer that is one of the unique compounds of the polyester family. Polyester resin is famous for its excellent combination of mechanical, chemical, and thermal resistance. PET is a recycled material that has enormous applications.
Recycled PET can be used for fabrics, fibre, sheets for manufacturing and packing automotive parts. PET is highly flexible, semi crystal, and colourless resin in its original state. As per processing, it becomes a rigid or semi-rigid material. It shows outstanding stability to moisture and alcohol solvent.
PET is famous for its higher heat resistance; thus, it has various unique applications. Crushed PET bottle grinding scrap is one of the valuable raw materials for making different types of plastic bottles.
The medical PET bottle is a good gas barrier that has excellent water vapour resistance quality.
Benefits of Using PET for Soft Drinks Bottle
PET is one of the most valuable materials for making soft drink bottles because of the following factors-
PET is a lightweight and cost-effective material to produce soft drinks bottles. It doesn’t get damaged during transportation.
It is durable and scratch-free. Due to its less breakable feature, it is less hazardous than glass. It makes the PET bottle more convenient.
PET is the latest innovation of science that is biodegradable and BPA-free that is not harmful to health. Maximum PET plastic bottles are recyclable that have several usages for beverage bottling.
Maximum soft drinks bottles are made from recycled PET plastic from household waste.
Manufacturers can make different shaped PET plastic bottles due to their flexibility.
PET plastic bottles are waterproof and corrosion-resistant.
Reason for Choosing Necessary Steps for Making Plastic Bottles
PET is a famous and safe polymer for making various bottles. In order to produce plastic bottles, PET must pass through polymerisation to make a long molecular chain. Diethylene glycol and acetaldehyde are the two common impurities that can damage the polymerisation process.
Good quality plastic bottles are essential to store cold beverages for a long time. Thus it is necessary to use these properties in an exact quantity to get good quality plastic bottles. Thus manufacturers always try to use unique steps to make authentic quality plastic bottles from PET.
Steps of Making Plastic Bottles from PET
The following steps are essential for making plastic bottles from PET.
Step1- manufacturers provide heat to PET to make them liquid. After that, they place the liquid PET in a tube-shaped mold called a parison. It is essential to pour the liquid PET into the tube for its perfect shaping after cooling.
Step 2- manufacturers heat the parison to convert them into a bottle-shaped mold. Manufacturers insert steel rods into the parison to allow air to enter the plastic. The molecules then polarise due to the high temperature and stretching and make a bottle.
Step3- manufacturers use unique substances to make the bottle cool to avoid creep. After step 3, manufacturers use various testing to ensure the safety features of the bottles. Transparency, gloss, impact resistance, creep resistance, and carbon dioxide permeability are the essential test for plastic bottles.
Drawbacks of PET Material
PET plastic is biodegradable and lightweight, but it has few drawbacks such as follows-
When manufacturers recycle waste plastics, the sorting process becomes difficult for the manufacturers. It can be costly and takes so much time.
Plastic burns quickly and creates so many harmful or toxic gases during burning. In such a situation, it can cause environmental pollution. Thus it is essential to follow unique steps to reduce the pollution level at the time of plastic burning.
Manufacturers use petroleum refining products at the time of making plastic bottles from crushed PET. Crushed PET bottle grinding scrap is helpful for making various plastic containers that aren’t harmful to your health.
From the above information, one can understand the usefulness of choosing authentic manufacturers while making PET plastic bottle for commercial health. Human health is a vital factor for plastic bottle manufacturers. Poor quality plastic creates many diseases; thus, it is essential to use authentic quality PET to make soft drink bottles.
