Polypropylene PlasticPolypropylene (PP) is a tough plastic that has excellent chemical resistance. PP is translucent in its natural state but can have a glossy finish when produced with color. Some examples of common products made with PP are dairy and medication containers. Polypropylene is suitable for hot fill applications of up to 205°F and is therefore great for autoclaving. It is not recommended for cold or sub-freezing temperatures. The Cary Company has an assortment of polypropylene plastics available for purchase, such as plastic caps and jars, which have a higher tolerance for chemical products. Discover if Polypropylene is appropriate for hot fill application by learning more about What Is Hot Fill Packaging and how it applies to Polypropylene containers.

What is an overseal ring?
Overseal rings, like Armlok® and Normlock™ rings, are plastic rings that secure paint can lids to prevent paint and coating products from leaking during storage and shipping. These seals add an extra measure of protection to securing the lid and are easily applied using a paint can closer or rubber mallet. When sealed properly, these rings are a key component to meeting many UN packaging requirements for metal paint cans.
Are these overseal rings made for all types of paint cans?
Armlok® and Normlock™ overseal rings are made for metal paint cans and lids. We also have some overseal rings made specifically for plastic or hybrid paint cans. These rings are sized for ½ pint, 1 pint, 1 quart and 1 gallon paint cans. If you’re considering an overseal ring as packaging for your product, you are welcome to request a sample to test the compatibility of your packaging with these seals.
How do you attach and remove these overseal rings?
Make sure the paint can lid is secure. To attach, place the ring on top of the can. Use a rubber mallet to secure ring onto lid. You can also use a paint can closer to apply the ring. To remove the ring, use pliers to grab the bottom edge of the ring and pry off. You can view a video of this process by clicking on the Videos tab of this product page.
What is the difference between Armlok® and Normlock™ rings?
Armlok® and Normlock™ rings are made by different manufacturers. They’re both typically made of high density polyethylene (HDPE), which offers durability and chemical resistance. Both types are used to secure metal paint cans. We also offer overseal ring options for plastic and hybrid paint cans.
Are overseal rings recyclable?
Our overseal rings are made of either high density polyethylene (HDPE) or polypropylene (PP) plastic, both of which are recyclable materials.
