PET plastic jars are widely used in the food, dietary supplement, cosmetic, and pharmaceutical industries for packaging. With high transparency, light weight, and excellent impact resistance, PET is one of the most popular packaging materials today.
Common Color Types of PET Plastic Jars
During production, the color of PET plastic jars is mainly achieved by adding color masterbatch. Different colors serve both decorative and functional purposes. The most common PET jar colors include:
Clear
Clear PET jars are the most popular type. They provide excellent visibility, allowing consumers to see the product directly inside. This makes them ideal for vitamins, candies, nuts, and coffee beans. Transparent packaging enhances trust and product appeal, especially for visually oriented brands.
Amber
Amber PET jars have strong UV protection properties, effectively shielding light-sensitive ingredients from oxidation or degradation. They are widely used for pharmaceuticals, supplements, and oil-based products - a classic choice for many medical and nutraceutical brands.


White / Opaque White
White PET jars offer a clean, minimal appearance that highlights labels and printed designs. They are common in cosmetic, dairy, and sports nutrition packaging. The opaque structure also provides moderate light protection.
Blue / Cobalt Blue
Blue PET jars give a refreshing and premium feel. They are often used for skincare, vitamins, and functional drinks. The cobalt blue tone stands out strongly on retail shelves and is especially popular in Western markets.


Green
Green PET jars convey a sense of nature and health, making them ideal for herbal supplements, organic foods, and eco-friendly products. Many brands prefer light green semi-transparent finishes for a balance between visibility and aesthetics.
Black / Smoke Grey
These darker PET jars are often used for high-end nutrition products, sports supplements, and men's grooming lines. They effectively block UV light while creating a professional and sophisticated image.
Color Production Methods and Process Differences
PET jar coloration is mainly achieved through two manufacturing methods:
1. Adding color masterbatch during injection or blow molding (Preform Coloring):
This is the most common approach. It provides consistent color and is suitable for large-scale production.
2. Applying surface finishing such as spray coating, UV coating, or electroplating:
This method enables metallic, matte, or gradient effects, ideal for customized or premium packaging lines.

In addition, Pantone Color Chart customization is fully supported. This enables manufacturers to create brand-specific shades that align with their corporate identity, product line, or market positioning. Pantone-matched PET colors help ensure visual consistency across global markets, making it an excellent choice for international brands or OEM clients.
Some manufacturers, such as Mingda Factory, also provide silk screen printing, hot stamping, and spray coating options, allowing brand logos, graphics, or anti-counterfeit marks to be applied directly onto the jar surface for added design flexibility.
