Cosmetic packaging Preform manufacturing at customer workshop#precisionmold #highprecisionmould

The reason why PET preforms are very demanding in the cosmetic packaging industry is mainly due to the following aspects:

1. High requirements for product characteristics:

Transparency: Cosmetic bottles need to show the appearance of the product, and the high transparency of PET preforms can meet this demand.

Chemical stability: Cosmetic ingredients are complex and diverse, and PET preforms need to have good chemical stability to avoid reactions with products.

Pressure resistance: Many cosmetic bottles need to withstand a certain amount of pressure, and the pressure resistance of PET preforms is directly related to the safety of the product.

2. High production process requirements:

Wall thickness uniformity: Uneven wall thickness will affect the strength and beauty of the bottle, so the wall thickness distribution is required to be uniform.

Surface finish: Surface finish directly affects the grade of the product and consumer experience.

Flawless: There should be no defects such as bubbles and impurities on the preform, otherwise it will affect the product quality.

3. High environmental protection requirements:

Recyclability: PET is a recyclable plastic that meets environmental protection requirements.

No harmful substances: PET preforms cannot contain substances that are harmful to the human body, such as heavy metals.
4. High aesthetic requirements:

Various shapes: In order to meet the packaging needs of different cosmetics, PET preforms need to have a variety of shape designs.
Surface decoration: PET preforms can be decorated with screen printing, hot stamping and other surface decorations to enhance the grade of the product.
