OSLO, Norway, July 1 (UPI) -- Sandwich makers in Norway won't have to worry about getting that last little bit out of their bottle of mayonnaise now that food brand Orkla has adopted a technology that lets the product simply slide right out of the packaging.
Orkla on Tuesday signed a licensing agreement with a Massachusetts-based company called LiquiGlide, which created a method to make the inside of certain food packaging permanently wet. The slippery interior surface of condiment bottles make it easier to squeeze out mayonnaise, mustard or ketchup without leaving behind any dregs.
"We chose to work with Orkla because they are an innovative and leading consumer goods company in the Nordics and the Baltics. Our exclusive agreement affirms that LiquiGlide's coatings create substantial value for consumers by enabling them to get every last drop."
LiquiGlide already has a number of agreements with other clients, including glue-maker Elmer's Products. LiquiGlide's website demonstrates a number of products -- including nail polish, hair gel, jelly and syrup -- that slip right out of containers both plastic and glass.
The way it works is that LiquiGlide adds a custom surface to the interior of bottles -- this surface combines both liquids and solids. The company uses different substances to create this surface depending on the needs of its client.
"The highly textured solid surface is composed of a matrix of features spaced sufficiently close to stably contain the impregnating liquid that fills in the spaces between the features," the company's website says. "The liquid is held in place within the texture, creating a permanently slippery, liquid surface. The product is actually sliding on our liquid layer, in a liquid-to-liquid interface."
LiquiGlide says the products it uses to create this surface are often made of natural substances like vegetable oil. All coatings for food products are Food and Drug Administration-approved and food-safe.
The company says the surface doesn't prevent plastic and glass bottles from being recycled.
"There is no additional effort necessary during the recycling process to remove LiquiGlide coatings from containers," LiquiGlide says. "The standard rinsing process works, and the materials in LiquiGlide coatings for recyclable containers are not harmful to the environment. The coatings should actually make the recycling process more efficient because there will be less product residue in the packages."
