Plastic bottles are the most commonly used container in the household sector out of the various metallic container, which is used for household needs. The name only tells us about the material it’s made out of. Typically, the plastic bottle used to hold liquids like potable water, milk, soft drinks, medicines, cooking oil, motor oil, ink, some cosmetic products like lotions, shampoos, etc. The size of the plastic bottles varies from small plastic bottles to a large carboy. Because of the material, the plastic bottles are both strong and light. You can easily carry this type of bottles in your handbag from one place to another.

History

In 1947, industries started to use plastic bottles for commercial purposes. But its cost was extremely high until the invention of HDPE that is polyethylene with high-density during the earlier 1960s.

Advantages

The introduction of new material immediately wins the favor of both the manufacturers as well as the customers. The main reason behind the increasing popularity of the plastic bottles was their light weight nature. The production and transportation cost is also relatively low as compare to the other metal containers. However, the main benefit of the plastic bottles as compared to the bottles made of glass is their superior ability of break resistant during the process of manufacture and moving. Because of these simple reasons, except for some alcohols, and it’s true that every other food industry has restored their food storage bottles with the plastic bottles.

Types

There are many types of plastic bottles such as Boston rounds, atomizer bottles, oil bottles, drinks bottles for pets, syrup bottles, round pattern bottles, bottles with tablet form, modern round shaped bottles, amber plastic bottles, etc., you can find in wholesale plastic bottles sector of a company.

Materials that is used for

To understand the manufacturing process it is necessary to know first the variety of techniques and materials used in the arrangement of the plastic bottles. The choice of the material used for the formation also depends upon the sole purpose of the bottles, which you are going to buy.

High-Density Polyethylene (HDPE): HDPE comes out as the most commonly used resin for the production of bottles made of plastic. This material is much economical, resistant to the collision, and also a good moisture barrier is provided by it. HDPE is translucent and flexible by nature. But an extra amount of color adds to the material will make it a bit non-transparent. It provides good protection under freezing temperatures. It is also compatible with the products like acids or caustics substance but not with the solvents. The safety of this material is approved by FDA.

Low-Density Polyethylene (LDPE): It is another type of material and is similar to high-density polyethylene in composition. LDPE is also very flexible and comparatively less resistant to chemical than HDPE. It is also classier than HDPE. Mainly LDPE is used for squeeze applications. This type of material is more expensive than high-density polyethylene.

Polyethylene Terephthalate (PET): This type of material is the one used for usual food stuff such as carbonated beverage, water bottles, and many others. PET provides an excellent barrier to alcohol and essential oils. It is resistant to some chemicals (although some will attack PET). It is also highly resistant to the collision. This material is not so good with the very high-temperature applications.

Polyvinyl Chloride (PVC): PVC is another type of materials used for the formation of plastic bottles. It provides oils and most glasses an excellent barrier. It has a very low oxygen transmission. Its drop impact resistance is extremely good. PVC is resistant to chemicals, but it is also very dangerous to some solvents. It is also not so good with high temperatures and incompatible with hot filled products. It has fallen on the list of infamy in recent times because of the potential health risks.

Polycarbonate (PC): It is a plastic material used to make bottles to hold water and milk. The 5-gallon plastic water bottles are the most familiar examples of polycarbonate bottles.

Stages to be followed

The production of the plastic bottles takes place in stages. Following stages are followed to form plastic bottles:

Choose the right material

Melting

Injection Molding

Stretch blow molding

Forming

Cooling

Physical Inspection

Trimming, and finally

Packing

Flexibility

Before finalized the material, a company needs to consider some important facts like weight, shape, cost and recyclability which will eventually change the ultimate price and the security of the product. In such a situation, the suitable benefit of using plastic is its flexibility. Glass bottles come out with different shapes and patterns due to which you can use it without any worries.

Thus, with the above discussion, it can clearly be seen that plastic always turns out as the prime choice material for the manufacturers as well as the customers, regardless of its results to the atmosphere.
