CKS Packaging Establishes Relationship With Barrier Plastics And BP Polymers.

CKS Packaging establishes relationship with Barrier Plastics and BP Polymers to offer Baritainer® Technology in Rigid Packaging Markets

CKS Packaging, in partnership with Barrier Plastics (BPI) and BP Polymers (BPP), will become a primary North American manufacturer of high density polyethylene (HDPE) rigid plastic containers utilizing BPP’s Quoral® Barrier Resin technology. These bottles will be marketed under the trade name, Baritainer®.

Both CKS and BPI will market the Quoral®/Baritainer® technology with BPI serving primarily as the technical arm while leveraging CKS’s sales and manufacturing capabilities.

The manufacturing partnership will focus on bringing a safe and more cost-effective alternative to end-users whose product requires varying levels of barrier protection against permeation. Plastic HDPE bottles made with the Quoral® barrier resin additive will provide packaging solutions for solvent-based products including household, industrial, agricultural, cleaning solvents, adhesives, wood preservatives and automotive additives. For these type products, Quoral® technology provides safe and functional containers at a significant cost advantage to traditional barrier methods such as fluorination, tin plate and PVC.

Dewayne Phillips, Executive Vice President for CKS Packaging, remarked of this manufacturing partnership: “Having the ability to produce Quoral® barrier resin bottles enables CKS to offer another value-added product solution to our customers and demonstrates CKS’ commitment to leading edge packaging technologies. We can now offer more cost effective supply chain solutions to our household chemical, industrial, and automotive customers who require barrier properties in their rigid plastic packaging.”

Kevin Callahan, Chief Operating Officer Barrier Plastics and BP Polymers, added, “We look forward to working with CKS in expanding and developing the Baritainer® product line and introducing it to new markets and opportunities. Both companies working together will offer a unique and proven barrier package technology to solve customer requirements in a very cost effective manner.”


Barrier Plastics was founded in 2008 after years of extensive materials research and product development. Based in California, Barrier Plastics is the sole US manufacturer of Quoral® BR Baritainers®. Barrier Plastics’ sister company, BP Polymers, LLC, is also located in Southern California. For more information, please visit us at or


CKS Packaging was founded in 1985 by Charles K. Sewell after selling his original start-up company Sewell Plastics which later became known as Constar Plastics Inc. CKS Packaging is based in Atlanta, Georgia and is a faith-driven company wholly owned by the Sewell Family. CKS Packaging is considered to be one of the fastest growing companies within the rigid plastics industry with manufacturing in 22 locations across the US.

Report examines use-phase GHGs for aluminum vs. glass, plastic | Greener Package

According to a new study conducted for the Aluminum Association by ICF International, the combined greenhouse gas (GHG) emissions associated with the transportation and refrigeration of beverages in aluminum cans are lower than those associated with that of beverages in glass or plastic bottles under the same conditions.

Update on Perfluorinated Grease-proofing Agents

Perfluorinated grease-proofing agents are coatings on paper wrappers and containers that come into contact with food, such as fast-food wrappers, microwave popcorn bags, and pet food bags. These coatings prevent oil and grease from foods from leaking through the packaging. Perfluorinated grease-proofing agents in various forms have been used on food contact surfaces since the 1960s.

How to Read The UN Rating Codes

Developed as a set of standards, by the United Nations, Un ratings are essential for shipping or storing hazardous materials. The UN Rating is a series of number and letter codes that show what a container is regulated to handle. They determine this through a series of tests that all containers must undergo if they are to be UN Rated. Current UN Regulations are enforced by the D.O.T. It is up to the filler of the product to determine what UN Rating they need.


+ Kortrax® BR is BP Polymer’s unique and proprietary barrier resin additive for high-density polyethylene (HDPE) that utilizes laminate technology thereby creating ‘Baritainers®.

+ Kortrax® BR is based on engineered grades of Polyamide (PA) 6.

+ Customized and proprietary manufacturing processing techniques are necessary to ensure optimal barrier performance in BPI’s Baritainers®.

+ The result is a laminar microstructure in which the Kortrax® BR forms stacks of large overlapping platelets or discontinuous layers within the Baritainer® wall which limit hydrocarbon permeation.   By creating a ‘tortuous path’ for large chain molecules, hydrocarbons attempting to diffuse through the HDPE walls into the atmosphere are stopped.

+ Standard Grades:
* Kortrax® BR 70 = for containers < 5 Liters.
* Kortrax® BR 50 = for containers > 5 Liters.

+ With the same processing conditions, the amount of barrier can be adapted by the amount of Kortrax® BR added.

+ In comparison with HDPE, Kortrax® is:
* Vs. Hydrocarbons (solvents) 100 times more efficacious.
* Excellent aroma barrier.
* 2x to 5x improvement in O2 barrier performance.

+ Properties of HDPE remain unchanged:
* Printability
* Mechanical Properties
* Colorants
* UV Additive
* Seal Properties
* Anti-Static Additive
* Fire Retardant Additive
* Recyclability
