Cream Jars for Cosmetics | PET Injection Molding

PEI cream jars are widely used in cosmetic packaging for products such as face creams, moisturizers, body lotions, and skincare products. With TEAM Rapid’s custom injection molding capabilities, we can help the customers to produce plastic jars in different sizes, shapes, colors, and specifications to meet packaging requirements.

Our Project Details:

PET Material Selection Based on Customer Requirements

Material selection for this project was based on the customer's specifications. We used PET (Polyethylene Terephthalate) as the raw material to build the molds, and then molded the cosmetic cream jars. Our manufacturing process follows the specified material and drawings requirements to ensure consistent product quality.

PET Injection Molding Process

PET injection molding involves melting dried PET resin and injecting it into a custom-made mold cavity. After cooling and solidification, the molded parts are ejected for further inspection.

In the production, we met the issues:

• Black Spots
• Bubbles and Silver Streaks.

Finally, we solved them by proper material drying, injection parameters, mold temperature, and cooling conditions to achieve consistent dimensions and surface quality.

Custom PET Cream Jar Manufacturing

TEAM Rapid manufactures custom PET cream jars according to customer-provided drawings, samples, and specifications. We support different jar sizes, shapes, colors, and production quantities based on project requirements.

Cosmetic PEI Low-Volume Injection Molding Capabilities

For startups and businesses launching new cosmetic products, we also offer rapid tooling and bridge production. Rapid tooling helps shorten mold manufacturing lead times and reduce initial tooling investment, while bridge production provides a practical way to manufacture small or medium batches before committing to full-scale production.

We also offer PEI low-volume injection molding for customers who need small batches of PET cream jars for market testing, product launches, or limited production runs.

Whether you are a startup developing your first cosmetic product or an established brand preparing for mass production, TEAM Rapid provides flexible injection molding and tooling solutions to support your production needs.

Frequently Asked Questions About PET Injection-Molded Cream Jars

Q: Is PET suitable for cosmetic cream jars?

A: Yes. PET offers good transparency, mechanical strength, and lightweight properties, making it suitable for many cosmetic packaging applications. However, material compatibility should be verified against the specific cosmetic formulation.

Q: Can PET cream jars be customized in different sizes and colors?

A: Yes. PET cream jars can be customized in different capacities, shapes, dimensions, and colors. Custom mold development allows manufacturers to produce packaging according to specific brand and product requirements.

Q: Can PET cream jars be manufactured using injection molding?

A: Yes. PET can be processed through injection molding to manufacture cosmetic packaging components. Proper resin drying, mold design, and processing parameter control are essential for achieving good part quality.

Q: Can TEAM Rapid manufacture small quantities of custom cosmetic cream jars?

A: Yes. TEAM Rapid supports prototype tooling, rapid tooling, and low-volume injection molding. Customers can start with smaller production quantities before moving to larger production volumes.
