Cap Liner Type:

SureSeal® SS-222 3-Ply Co-extruded Foam Liner Composition
The SureSeal® SS-222 liner is a three-ply co-extruded white liner consisting of a closed cell foam produced from low-density polyethylene (LDPE) faced with solid LDPE on both sides. The opaque white outer skins create a high-quality visual aesthetic. The inner foam core creates a compressible yet resilient product allowing it to create a good seal with the container. 3-ply foam liners have become the industry standard due to there all-purpose compatibility, resilient, compressible seal, cleanliness (no pulp dust) and economy. 3-ply liners are taste and odor resistant, and have a low moisture transmission rate, meaning they prevent moisture from entering the bottle and affecting products. (This liner does not create an airtight seal.)

Explore What Is Considered a Tamper-Evident Container and Why They Matter for a better understanding of the characteristics of a tamper-evident container. When in doubt, consult our Guide to Types of Tamper Evident Packaging or 5 Tamper-Evident Packaging Examples for Enhanced Product Security to discover the kinds of tamper-evident packaging available for all industries.


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.

Q & A
Customer Questions
Is there a recommended torque setting for the 38mm Drop-lok White Ribbed Plastic Cap w/Foam Liner?
Thank you for your inquiry. Assuming this cap is going on an HDPE 1787 neck finish bottle, the recommendations are:
Application torque -- 18-22 inch pounds
Removal torque -- 9-15 inch pounds (immediate)
Removal torque -- 9-24 inch pounds (after 24 hours)
Incremental torque -- 22-26 inch pounds
Visual check should include:
*No bulging of closure caused by excessive torque or cocked cap.
*Liner impression should be uniform and distinct as examined from top side.
*No broken bands or bands hanging down.
*Squeeze bottle to confirm seal.
*Verify tamper-evidence function by removing closure - 50% of bridges should break.
