How a PET Blowing Machine Can Help You Create a Bottle That is Unique to Your Brand

PET is a common material used in the manufacture of bottles and cans. There are two main production processes for producing these: injection molding and blow molding.

Injection molding uses raw plastic pellets to produce solid parts, while blow molding uses hollow parts made from melted plastic. The choice of which process is best for you depends on the machinery and desired bottle products.

1. Bottle size

PET, also known as polyethylene terephthalate, is a polyester used for plastic bottles and containers. It is a highly favored resin due to its many benefits, including high impact resistance and low moisture absorption.

In a two-stage PET stretch blow-molding process, an injection-molded preform is heated via metal sheath heat, quartz heat or radio frequency (RF) heating to the orientation stretch blow-molding temperature for the material being processed. The preform is then equilibrated to the proper orientation and transported to the blow-molding area for expansion.

The bottle is then blown. If the preform is not blown correctly, the bottle will have a very uneven wall thickness. This is because the inside surface of the preform tends to be cooler than the outside and therefore does not stretch as easily. This produces thousands of microfractures which affect the passage of light.

2. Bottle shape

A PET Blowing Machine can help you create a bottle that is unique to your brand. That's because a PET bottle can be designed with a distinctive shape that is easily identifiable on the shelf.

Using a bottle with a distinctive shape can also help you stand out on the shelf and attract more customers. Think about how soft drinks manufacturers like Coca-Cola and Orangina have used different bottle shapes to drive sales.

In most cases, the bottle shape you choose is dependent on your budget. For example, if you want a blemish-free bottle, in a precise oblong shape, with a sturdy thread and at a low capital cost, then a single-stage blow molding machine is best for you.

3. Bottle material

Plastic bottles are increasingly popular for a variety of reasons, including their attractive appearance and portability. They are also cheaper than glass or aluminum.

In addition, they are recyclable, which saves energy and reduces the amount of raw material needed for packaging.

Compared to other bottle containers, PET bottles are lightweight and safe. They also have a higher level of transparency, making them easier to see what’s inside.

The process used to make PET bottles is called blow molding. The method is a two-step process, which requires the use of preform injection and bottle blowing machines.

4. Bottle color

PET plastics are lightweight and durable, making them popular for a wide variety of packaging needs. They can also be colored for added branding opportunities.

In addition to its versatility, PET plastic bottles are also hygienic and recyclable. The material is used for a wide range of products, including food and beverages, cleaning products, and cosmetics.

A new study found that the color of rPET pellets is dependent on their processing. When preforms are exposed to high temperatures, the materials are susceptible to thermally induced degradation reactions, such as yellowing and lower IVs.

This is why automated management of the process is critical to ensuring bottle quality and consistency. This means monitoring rPET process variations in real time and adjusting the blowmolder automatically to respond.

5. Bottle shape design

PET blow moulding is a flexible manufacturing process for creating high-quality bottles in a wide range of shapes. It allows for the production of bottles that stand out on supermarket shelves and promote a brand.

The process consists of making a test-tube-like preform, which undergoes a stretch-and-blow molding process. This method produces a bottle that has good optical and barrier properties.

It is important to design the preform correctly and based on empirical data on how much each specific PET needs to be stretched in order to reach its natural stretch ratio. This will influence the bottle’s weight distribution and also the thickness uniformity of its shoulders and base.
