The clear PET square jars are available w/ black polypro PS22 lined caps. The PS22 liner is pressure sensitive and adheres to the container once the closure is properly applied. When the cap is removed the seal remains on the container with the words "Sealed for Your Protection" written on the seal facing up. This can be removed by simply peeling off. The square jars are available in 4, 8, and 16 oz sizes. Use the clear PET square jars w/ black caps to package and display products such as creams, lotions, body scrubs and more!
