Kosmetech specializes in a series of small cosmetic and skincare jars for your sampling and packaging needs. Our small sample jars are economically priced and a great way to give away a sample of your product. Kosmetech also carries a large selection of stackable jars (or multi-stack jars) with various assembly options providing the versatility for your specific requirements.
It is always best to request samples of our jars prior to purchasing. This is to ensure that the product you are packaging is compatible with ours. Kosmetech makes no guarantees written or implied as to the compatibility of the plastic jars or containers it sells with the customers intended use. There are always limitations in the use of ALL plastic materials, therefore, we always recommend that you request samples for compatibility testing. You can request samples of any specific item at its detail page and they are shipped to you at no cost.
Below is a basic guide to resin materials that are used in our jar products. This guide might provide some insight or some helpful hints as to the possible limitations in your choice of packaging or sampling your products:
- Polystyrene (or styrene, PS): Polystyrene offers excellent clarity and stiffness at an economical cost. It is commonly used with dry products (eyeshadow, glitter, powder, etc), but often used for sampling creams. If your cream contains oils or has a liquid consistency, polystyrene is not a good choice for packaging. As an alternative, you may want to use a polypropylene jar instead that has a better chemical resistance.
- Polypropylene (PP): Polypropylene is a more stable plastic than Polystyrene. This plastic resin provides an excellent moisture barrier and has excellent chemical resistance.
- Urea formaldehyde (UF): This form of polymer is strong, durable and has a glossy finish. They are not generally affected by oils and exhibit a good resistance to most skincare products.
- Styrene-Acrylonitrile (SAN): This is a combination of polystyrene and Acrylonitrile. The polystyrene portion provides the clarity and stiffness, while the acrylonitrile portion provides good chemical resistance. This gives you a little better impact strength than polystyrene alone.
