Consider 8 oz clear PET straight sided plastic jars and black PS22 lined plastic caps for body care products, bath salts, skincare products, and more. Clear PET straight sided jars are highly durable, provide barriers against gas and moisture, and have good resistance to heat, dilute acids, oils, and alcohols. 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.
