Info PE & PET

PET, also known as polyethylene terephthalate, is a commonly used plastic for the production of dropper bottles. It has a variety of properties that make it an ideal choice for this use.

One of the most important features of PET is its high chemical resistance. It is resistant to many acids, bases, and organic solvents, making it a suitable choice for storing chemicals and other substances. It is also very stable and has high mechanical strength, meaning it is not easily damaged or broken.

Another important feature of PET is its high clarity and transparency. It is a virtually colorless plastic that allows the contents of a dropper bottle to be easily seen. This is important when it comes to monitoring the fill level of the bottle or ensuring there are no contaminants present.

PET is also lightweight and has good dimensional stability. These properties make it a suitable choice for the production of dropper bottles as they are easy to transport and use.

Another important feature of PET is its environmental friendliness. It is fully recyclable and is often reused in the production of other plastic products. This helps to reduce environmental impact and conserve resources.

Overall, PET offers a variety of properties that make it an ideal choice for use in dropper bottles. It is chemically resistant, stable, transparent, lightweight, and environmentally friendly. All of these properties contribute to it being one of the most widely used plastics in the industry.

 

PE, or polyethylene, is an important plastic that is used in many industries, including the production of dropper bottles. PE has a number of positive properties that make it a popular choice for the production of dropper bottles.

One of the key properties of PE is its flexibility. PE is a very elastic plastic that can be easily molded into various shapes and sizes of dropper bottles. This makes it an ideal choice for packaging liquid products that are needed in different sizes and shapes.

Another advantage of PE is its strength and durability. Despite its flexibility, PE is also very sturdy and can withstand many stresses without damaging or breaking. This makes it an ideal choice for packaging products that may be subjected to strong stresses during transportation or storage.

PE is also very resistant to chemical substances and can therefore be safely used for packaging chemical products. It is also tasteless and odorless, making it suitable for packaging food.

Overall, PE offers many positive properties that make it a popular choice for the production of dropper bottles. It is flexible, strong and durable, resistant to chemical substances and tasteless and odorless, making it suitable for a variety of applications.
