Protective Film Factory is a PA PE Thermoforming Film Manufacturer supplying multilayer rollstock for automatic food-packaging lines. The range covers PA/PE forming bottom web, PA/EVOH/PE high-barrier film and matching non-forming top seal film for vacuum and modified atmosphere packaging (MAP). Film structure, thickness, web width and forming depth are matched to pocket geometry, packed food, storage conditions and machine settings. Samples can be prepared for product and machine trials before scheduled production.

This plastic film for thermoforming is used on lines where the lower web is heated and drawn into pockets, then sealed with a compatible upper web. PA contributes strength, forming stability and puncture resistance. PE provides the sealing surface. An EVOH barrier layer can be introduced when oxygen control and shelf-life targets are more demanding. The suitable construction depends on the packed product, storage temperature, distribution route and packaging method, not on nominal thickness alone.
The thermoforming PA PE film range includes standard PA/PE flexible bottom web, PA/EVOH/PE high-barrier forming film and matching top seal film. Standard-draw grades suit shallow cavities and smooth products. Deep-draw grades are more suitable when pocket depth, corner radius or product shape increases sidewall-thinning risk.
Top webs can be transparent, tinted, peelable, non-peelable, anti-fog or printed. Plastic sheet film roll formats and LDPE rollstock can also be discussed when related converting support is required, while the main category remains focused on thermoforming webs.
Start with the packed food, packaging method and line conditions. Standard PA/PE suits vacuum packs where formability, puncture resistance and sealing need to remain balanced. Select PA/EVOH/PE when oxygen barrier, aroma retention or shelf-life targets are more demanding, especially for MAP projects.
Avoid choosing a deep-draw grade from nominal thickness alone. Specify pocket length, width, depth and corner radius. After forming, inspect the pocket bottom, sidewalls and corners for thinning, whitening, pinholes or distortion. Bone-in products and sharp profiles also require a puncture review. Before volume production, check top-web compatibility, sealing-temperature window, dwell time and pressure. Web width, roll diameter, core size and unwind direction must fit the intended equipment.
Seal integrity should be reviewed as a combination of film structure, seal-layer compatibility and operating conditions, rather than as a single strength value. Check the top web, sealant side, sealing-temperature window, dwell time, pressure and packaging speed on the intended line. Compare cooled seal strength, hot-tack behavior and failure mode. Finished vacuum or MAP packs should also be checked for incomplete sealing, channel leaks and gross leakage, especially where oil, moisture or food residue may enter the seal area. Record the approved result together with the machine settings used during the trial.

Protective Film Factory can finalize the film structure and rollstock specification around the packed product, line conditions and approved trial result. Web width, roll length, core size, outer diameter and unwind direction should be recorded with the retained sample before repeat production. Transparency, printing, anti-fog treatment and peel behavior can be reviewed where required. Where the sourcing scope also includes support normally handled by an LDPE plastic film manufacturer, LDPE rollstock can be discussed separately without changing the main thermoforming-web selection. Approved specifications should remain traceable across future batches, including roll labels, retained samples and the line settings used during validation.
Forming depth should be assessed after heating and drawing, not from flat-film data alone. Use the intended pocket geometry and machine settings, then compare the pocket bottom, sidewalls and corners for uneven material distribution. For sharp product profiles, review puncture risk after forming. For PA/EVOH/PE grades, barrier performance should also be checked after deep drawing where required. Retain the approved structure, trial record and forming conditions as the reference for repeat production.
PA/PE balances forming strength and sealing performance. PA/EVOH/PE adds an oxygen-barrier layer for applications with more demanding shelf-life requirements.
Yes. The top web can be matched according to sealing layer, peel behavior, transparency, printing and anti-fog requirements.
Provide the packed product, vacuum or MAP method, machine model, pocket dimensions, forming depth, web width, roll diameter, core size and unwind direction.
Keep the approved sample, structure, dimensions, forming conditions and sealing settings as the repeat-order reference. Maintain batch traceability.
