Flexible coextruded thermoforming films

Bottom films for MAP packs that need clean forming and reliable seals.

Nexus supplies 5 and 7 layer PA/PE and PA/EVOH/PE bottom films in 50 to 250 microns for food packs on horizontal thermoforming lines. Film choice depends on forming depth, product shape, puncture risk, lidding-film compatibility, MAP gas mix, storage condition, and shelf-life target.

Selection logic

Start with the product, cavity, top web, and shelf-life target.

A bottom web is part of a complete MAP pack, not a standalone roll. The product, cavity depth, seal system, storage route, and shelf-life requirement should set the structure and thickness range before sampling.

Pack format

Product weight, cavity shape, forming depth, and pack dimensions set the first film and gauge range.

Product sensitivity

Oxygen, moisture, oil, aroma, bones, and product edges decide the need for barrier or added toughness.

Top-web match

The PE seal layer must suit the selected lidding film, seal type, and expected operating window.

Storage route

Chilled, frozen, export, and MAP conditions affect final barrier, gauge, and handling requirements.

Structures

Select the barrier level around the product and shelf-life brief.

Nexus supplies flexible thermoforming films in 50 to 250 microns. PA/PE is the standard barrier option for strong, clear forming packs. PA/EVOH/PE is specified when oxygen control is central to the MAP shelf-life plan.

Standard Barrier - PA/PE

For clear forming packs where toughness and sealing are the priority.

PA/PE is used for dairy, meat, seafood, and date packs where the main requirements are formability, puncture resistance, clarity, and dependable sealing to the top web.

  • 5 and 7 layer coextruded options
  • 50 to 250 micron thickness range
  • Common starting point for MAP and chilled food packs
High Barrier - PA/EVOH/PE

For oxygen-sensitive packs where shelf life drives the structure.

PA/EVOH/PE is used when oxygen-barrier performance is part of the commercial specification, especially for MAP packs, export movement, and stricter shelf-life requirements.

  • 5 and 7 layer coextruded options
  • 50 to 250 micron thickness range
  • Confirm with product, lidding film, gas mix, and shelf-life target

Performance priorities

What the bottom web must prove on the line.

After the structure is shortlisted, the pack trial should confirm how the bottom web forms, seals, resists handling stress, and supports the required MAP shelf-life target.

Corner strength after forming Maintains strength in drawn corners instead of thinning into weak points.
Seal compatibility Runs with the selected lidding film, seal profile, temperature window, and pack format.
Puncture resistance Protects against product edges, firm foods, chilled logistics, and export handling.
MAP shelf-life support High-barrier options are used when oxygen control is part of the target.

Where it fits

Applications where product shape, shelf life, and presentation all matter.

Flexible thermoforming films are used across regional and global food categories. Dates are especially relevant for the Middle East, North Africa, and India, while dairy, meat, poultry, and seafood remain core MAP packaging applications worldwide.

Technical remarks

Final film selection should be confirmed against the actual product and line conditions.

Flexible thermoforming performance depends on product shape, pack weight, forming depth, forming temperature, bottom-film width, seal area, lidding-film structure, MAP requirement, storage temperature, shelf-life target, and handling risk. Samples and trial thickness should be chosen from these details, then validated on the customer’s line.

Requirement checklist

Share these details before we recommend a film.

The right forming film is easier to shortlist when the product, cavity, lidding film, and storage conditions are clear from the start.

01

Product and pack format

Product type, filled weight, pack dimensions, cavity shape, and MAP or vacuum expectation.

02

Machine and forming depth

Bottom-film width, forming depth, forming temperature range, line speed, and machine format if known.

03

Lidding film and seal needs

Top-web structure, peel or weld seal preference, seal-area contamination, and leak concerns.

04

Storage and shelf life

Chilled, frozen, ambient, or export transit conditions with gas mix and shelf-life target.

FAQ

Common questions before sending a forming-film requirement.

What thickness range is available?

Nexus flexible thermoforming bottom films are listed from 50 to 250 microns. The final thickness should be selected according to forming depth, product weight, pack size, puncture risk, and shelf-life target.

Which structures are listed?

The listed structure families are Standard Barrier - PA/PE and High Barrier - PA/EVOH/PE in 5 and 7 layer coextruded options.

Are these films mainly for MAP packs?

Yes. This page is positioned mainly for MAP packs on horizontal form-fill-seal thermoforming lines. Final suitability should still be checked against the product, lidding film, cavity design, and storage plan.

Is a technical data sheet available?

Yes. The PA/PE flexible forming films technical data sheet is available from this page and the Downloads section.
