TPX-PP Lamination Film
Dual-ovenable lamination film for pulp-molded food containers, withstanding temperatures up to 160°C. Cuts plastic usage by up to 85% versus traditional plastic trays while adding full microwave-and-oven capability and an FDA-approved anti-migration food-contact layer.
The Mid-Gauge Dual-Ovenable Film for Sustainable Pulp Containers
F4407 is the mid-gauge grade in Intlpak's TPX-PP lamination family, between F4408 (35μm) and F4403 (70μm), bonding a food-contact PP/TPX layer to a plant-fiber base. Where a standard pulp container is typically microwave-only, this lamination upgrades it to fully dual-ovenable up to 160°C, and the FDA-approved food-contact-grade TPX blend improves thermal stability while helping prevent additives from migrating into high-heat, high-fat foods.
Where F4407 Is Used
- 1 Ready-to-eat and fresh convenience meals
- 2 Frozen-to-oven entrees
- 3 Premium takeout and catering services
- 4 High-fat dishes, curries, bento meals, and bakery products

Questions About F4407
Across the 35/50/70 μm TPX-PP grades, where does F4407 sit?
It is the mainstream grade. At 50 μm it falls between F4408 (35 μm) and F4403 (70 μm), and it carries both a stated heat rating — up to 160°C — and plastic reduction of up to 85%. Most molded fiber meal tray projects start their evaluation here, then move up or down with container weight and heating intensity.
Is the 160°C dual-ovenable rating for the film or the whole container?
For the finished laminate on a molded fiber container. F4407 is specified as microwave- and oven-safe to 160°C, but real performance depends on lamination quality, the fiber substrate and heating time. Test with your actual container and heating profile — temperature, duration, fat content — rather than inferring from the film specification alone.
How is the 85% plastic reduction calculated?
As a comparison against a conventional all-plastic tray. The container body becomes molded plant fiber, leaving only a thin food-contact film as plastic, so total plastic drops sharply — the finished TPX-MFC container in this family measures 10.75% plastic content against 100% for a conventional PP container. The exact ratio varies with container size and film gauge.
What food-safety role does the TPX layer play?
Migration blocking. The food-contact surface is an FDA-approved food-grade TPX co-extrusion intended to suppress additive and microplastic migration into food under high heat and high fat. That is the principal difference between this family and ordinary PP-coated paper containers, particularly in oven-heated applications.
F4407 and F4403 are both oven-safe — which should I take?
Container specification and cost decide. F4403 at 70 μm gives a heavier film layer for larger, heavier or high-fat meals; F4407 at 50 μm is sufficient for most standard tray sizes and uses less material. For maximum light-weighting, evaluate F4408 (35 μm) — noting its heat and plastic-reduction figures are not yet published.
