Choose clear 12 oz PET straight sided plastic jars with black PS22 lined plastic caps for a range of products. Clear straight sided jars have tall walls for custom labeling and are composed of PET which provides barriers against gas and moisture, and have good resistance to heat, dilute acids, oils, and alcohols. The PS22 liners apply to plastic jars without the need for machinery and provide an additional layer against outside elements, such as oxygen and moisture, which can help preserve freshness. Consider these plastic jars with black plastic caps for body care products, CBD candies, and more.
