How to make latex gloves

Tapping a rubber tree

There have been many substitutes for latex gloves over the years – nitrile, synthetic and vinyl. No matter how appealing these other types may be, latex gloves still have many qualities that make them more superior. With our own plantations in Sri Lanka covering 17,000 acres and producing 12,500kgs of latex per day, we are confident in the knowledge that our nursery grown trees produce some of the best latex in the world.

Latex is produced naturally from rubber trees and extracted by a method called “Tapping”. Every three days the bark of a rubber tree can be tapped by using a special rubber tapping chisel/knife. Running down at an angle of approximately 35 degrees half way around the circumference of the tree, the top layer of the bark is lightly cut away. A vertical canal or trough then leads down from the scored tree-bark towards an embedded metal shaped funnel which protrudes over a supported container.

Once the tree bark has been “Tapped”, the raw latex within the bark runs along the gradient, down the vertical canal onto the funnel and into the container. The latex is then collected and transferred to larger containers for shipment to our centrifuged latex factories, where the natural latex is converted into latex concentrate which is done through the extraction of excess water and by increasing the rubber content of the latex. Proteins are also stripped from the latex to an absolute minimum, which ensures the latex is flexible and strong enough for the end product.

From there it’s transferred into “Dipping Tanks”, where thousands of automatically pre-cleaned and brushed ceramic hand “forms” on a spinning production line in various size sections  are lowered and dipped into the liquid latex to form the gloves. The gloves then pass through ovens on the production line to bake which makes the latex harden. The baked gloves on the forms then pass through alkaline tanks and cleaning tanks before being transferred automatically to the beading unit which helps the end user don the glove.

The production processes adhere to the highest global quality standards. All production plants are ISO 9001:2008. In particular, the medical gloves are ISO 13485 certified. Every 100th glove is tested for AQL 1.5 by water containment and compressed air inflation. This ensures that, should there be any inconsistency with quality, it can be identified immediately thus further guaranteeing quality.

Our laboratories also continually test the latex throughout every manufacturing process which enables us to gauge protein content, tensile strength and ensuring the highest latex quality used in the end product. Again, should anything arise that’s untoward we can identify it immediately and halt the production process.

As latex is naturally flexible, our gloves a user wears offers the highest tensile strength, greater comfort and a closer fit, and with our stringent quality levels we can guarantee high personal protection with no leakage or penetration.

All in all, our powder free latex gloves are your natural choice for protection.
