our range of waxes, hot melts and water based coatings

Our Paraflex™ coating wax range includes

  • Paraflex™ CW  - non-sealable waxes for gloss & barrier
  • Paraflex™ WS   - waxy peel-seal grades
  • Paraflex™ HS    - high-strength heat seal hot melts

A wide range of Paraflex™ CW types are available for different types of paper, machine viscosity and balances between gloss and scuff resistance. These waxes are used for twist, fold, bunch and sachet wrappers for sweets, meat and cheese wrappers, flower wrappers, technical wrapping papers and decorative papers.

Our Paraflex™ WS and Paraflex™ HS heat seal waxes and hot melts also provide gloss & barrier performance combined with tailored heat sealability for a wide range of applications.

Paraflex™ WS can be used for either single or double-side coatings to provide an easy-open, peel-seal coating for the packaging of, for example, bread, sweets and chewing gum.

Paraflex™ HS grades offer a higher sealing strength and specific adhesion to a broad range of both polar and non-polar substrates, such as PE, PP, PS, PET, PLA, glass and aluminum. Common applications for the Paraflex HS range of products include yogurt banderole (in-mould labelling / IML), soap wrappers, lidding, cap seal liners or in-register coated confectionery laminates.

The differences between the various grades relate to the properties required in the wax coating and also the machinery employed. The main performance criteria for gloss and heat seal coating waxes are:

Coating requirements

  • rheology
  • thermal stability
  • operating temperature
  • non-blocking

Packaging machine requirements

  • scuff resistance
  • controlled COF(c/c c/m)
  • heat sealability
  • hot-tack
  • deadfold and twist retention
  • wide operating window

End-use requirements

  • moisture barrier (MVTR/Cobb)
  • release against the packed product
  • tailored gloss levels
  • organoleptics
  • regulatory compliance e.g. direct food contact approval

Paraflex NOWAX™ vegetable based waxes offer a sustainable answer to a host of today’s packaging challenges with a positive consumer image. These coating waxes provide paper-based packaging with the needed functionality like controllable barrier properties, high gloss levels, excellent release characteristics and bring additional machineability benefits like low coefficient of friction, good scuff resistance and heat sealability. They can be run on existing wax coating equipment and depending on applied coating weight, can meet all renewability and ‘end of life’ requirements.

Paramelt have developed a comprehensive range of Paraflex Nowax grades to offer equivalent functionality to traditional mineral wax-based Paraflex coatings.

Compared with standard Paraflex grades, vegetable-based Nowax solutions offer a number of advantages in the delivered functionality.

The Paraflex™ L and Paraflex™ LT range of laminating waxes includes a number of different grades to address various specific requirements within the flexible packaging industry.

The standard Paraflex L range provides laminating waxes for use with many different substrates including paper, aluminium foil, paperboard, cellophane and plastic films (PE, PP, PS, PET, PLA) depending on the target complex. Wax laminated structures are used in a wide variety of end-use applications such as butter and margarine wrappers, confectionery packaging, biscuit and cheese wrappers, bouillon, soup and stock cubes.

Variants in the Paraflex™ L range are designed to deliver a number of specific performance requirements:

  • Specific substrate adhesion
  • Lamination bond strength
  • Fat & moisture resistance
  • Heat resistance
  • Application temperature
  • Good organoleptics for sensitive products

The Paraflex™ LT range has been specifically developed to offer effective lamination and subsequent controlled delamination in cap-seal liner wads.

Paramelt offers a number of products balancing cost and performance in relation to die cutting resistance, heat resistance, bond strength and subsequent release. Liner wads are widely used as an induction sealable closure element in combination with screw caps. Typical examples are lubricants and household chemicals, cosmetics and pharmaceuticals, instant-coffee jars and high-fat spreads.

In addition to cap-seal liners the ability of these waxes to ‘strike-through’ the paper-based substrate has also found application in heat-sealable laminates, for example between silk paper and aluminium foil.

The Aquaseal packaging coatings range is based on a unique, proprietary, high-solids mechanical dispersion technology. This platform enables the production of water-based dispersions of high molecular weight, thermoplastic polyolefins and styrene block copolymers in water.

These unique polymer dispersions bring significant advantages over existing solvent-based lacquers, water-based emulsions and extrusion coatings for the conversion of paper, film and foil.

A number of key applications have been developed for each of the principal flexible packaging substrate types.

Paper coatings

A number of Aquaseal grades are available, based on extrusion grade polyolefins such as Surlyn™ ionomers, EAA, mLD-PE, PP and EVA. These materials offer a number of potential benefits such as heat sealability, moisture barrier and recyclability.

In contrast to typical paper coatings based on water-based emulsions, such as acrylic and PVDC, Aquaseal functional coatings offer superior humidity resistance and hot-tack performance, equivalent to extrusion coated papers.

A range of Aquaseal grades are available for:

Heat sealable papers
