Synthetic latex and wax emulsions for contact with food

REPSOL REDEMUL RUB is a water-based emulsion of copolymers and paraffins designed to be applied as a coating for containers and, in particular, those aimed at the food industry, for which reason they comply with the FDA Regulations and the Codex Alimentarius for products that come in contact with food.

REPSOL REDEMUL RUB is formulated based on a mixture of carefully selected and treated copolymers and waxes that guarantee the best waterproofing performance for containers by forming a hydrophobic and oleophobic coating or film on its surface. This effect can be controlled through the amount of product added, with the ability to obtain a water-repellent paper or cardboard surface. The package of surfactants used to emulsify these copolymers and paraffins has been selected to ensure product stability during both transport and handling.

REPSOL REDEMUL RUB is characterised by its great coating capacity; excellent barrier effect against grease, oil and water vapour; non-slip effect; great stability during handling and storage; and good resistance to hard water. REPSOL REDEMUL RUB is especially suitable for coating all types of paper and wood or cardboard boxes to transport food and, in general, for any type of application in containers that may come in contact with food.
It is applied with the same techniques as traditional paraffin emulsions used in the paper and/or cardboard industries.

Paper and cardboard

Repsol markets special waxes for the paper and cardboard industry in two different formats: liquid and solid. These coating products for paper/cardboard improve their water repellent properties and increase their mechanical resistance (hardness, resistance to pressure, etc.).

Ranges

Repsol Redemul range

In liquid format (aqueous emulsion type) for cold application.

Redecoat range

In solid format to be applied melted.

Benefits

When foods like fruits and vegetables ripen, they eliminate water that may deteriorate the container they are in. Therefore, if the paper or cardboard are protected with an adequate coating, both the container and the food it contains are also protected.

Applications

Within this wide range of products each one is used with a specific application, such as:

  • Food Wrapping

  • Waxes for decorative papers

  • Coatings for paper/cardboard cups

  • Additives in paints, varnishes, and glues

  • Corrugated carboard

Application methods

The methods to apply these products on paper and cardboard are the typical ones used in the industry to apply coatings.

  • Curtain

  • Scraper

  • Rotary cylinders or rollers

  • Anilox

  • Inmersion
