How we managed to produce biodegradable straws with good strength

"One of the things we always want as customers is for the characteristics offered in a technical data sheet to be met in practice. With you, we feel that guarantee" Production Plant Manager Orlando Perez.

For years, many companies in Colombia —especially in sectors such as petrochemicals, the food industry and chemicals— depended on imported industrial containers. This meant high costs, long wait times and uncertain logistics.

No one in the country produced these containers with the necessary technical specifications. The closest alternatives were recycled solutions, expensive and of low quality. There, one of our customers found an opportunity that they managed to capitalize on with a reliable supplier, Esenttia

An encounter that changed everything
Less than a year ago, in the midst of a search for cap materials, the plant manager of Rexiplas, Mr. Orlando Perez, approached us. In that initial conversation, they learned about our portfolio and, together with our commercial and technical support team, we identified a resin that would mark a before and after: a high molecular weight, low melt index polyethylene, the HDPE ESENTTIA S10-50 HL — this technical property was the key to producing stronger, cleaner and more process-stable containers.

From testing to final product
Up to that point, Rexiplas had worked with imported materials seeking low Melt Index to withstand between 1 and 1.5 tons per container, finding in the HDPE ESENTTIA S10-50 HL an appropriate balance that allowed them to satisfactorily meet these requirements for the development of their IBC tank

Together, we found a solution with outstanding characteristics:

Oxidation resistance and high temperature performance
Excellent resistance to high temperatures, which allows greater incorporation of recovered material from the same process without affecting its mechanical properties or OIT (Oxidation Induction Time) values, while also ensuring a great appearance in the final product
Parison stability, preventing droop and ensuring excellent dimensional stability
Perfectly sealed folds
Natural white color (no pigments needed)
And most importantly: stronger, cleaner containers and even more competitive prices than imported ones, thanks to local production and nearby distribution centers that ensure quality raw materials to meet market expectations

A real transformation
Customers like "Derivados del Petroleo" stopped importing to trust in this local solution. The results were clear: better performance, lower cost and greater operational stability.

Thanks to our partnership, Rexiplas achieved:

Total use of regrind without oxidation
More stable and cleaner blow molding processes
Waste reduction and shorter production times
Material that maintains its properties even at high temperatures
Why Esenttia?
What sets us apart is simple:

Immediate deliveries, without depending on customs or ships
Technical support that backs every specification
National logistics that responds even during shortages
In an uncertain environment, we offer certainty.

What's next?
Today, Rexiplas already distributes its products nationally and is even evaluating the possibility of exporting to countries in the region. Additionally, they are considering setting up their own laboratory to further strengthen the traceability of their processes and offer their customers an additional guarantee based on real results.

This case demonstrates that, with strategic partners and innovative materials, transformation is indeed possible.

At Esenttia, we are proud to be part of that story
