Top Seal Solutions for Thermoforming Packaging
In the world of thermoforming and vacuum packaging, non forming film โ also known as top web film โ plays a vital role in ensuring seal integrity, product safety, and shelf life. Used in tandem with forming film, non forming film covers and seals the product during horizontal form-fill-seal (HFFS) or vertical form-fill-seal (VFFS) operations.
At Sunrise Packaging Films, we engineer high-performance non forming films that eliminate leaks, improve visual appeal, and help reduce failed packaging incidents across food, medical, and consumer industries.
What Is Non Forming Film?
Non forming film is a flat, flexible plastic film used as the top layer in vacuum or thermoformed packaging. Unlike forming film, which is molded to the shape of the product, non forming film remains flat and is heat-sealed to the pre-formed base layer to enclose the product securely.
Itโs the protective skin that preserves freshness, prevents contamination, and delivers that final visual touch that sells the product on the shelf.

5 Essential Questions to Ask Before You Buy Non Forming Film from a New Supplier
When it comes to high-speed, form-fill-seal packaging, choosing the right non forming film supplier can make or break your production line. At Sunrise Packaging Films, we help manufacturers avoid downtime, reduce waste, and optimize machine performance with custom-engineered films. But before you make a switch, here are five essential questions to ask any supplier offering non forming film.
1. Is the Film Optimized for My Equipment?
Not all non forming films perform equally on every machine. Whether you’re using Multivac, Reiser, or ULMA equipment, your film must match specific dwell times, tension settings, and sealing parameters. Ask your supplier whether the film has been tested and dialed in for your exact setup.
2. Can You Provide Barrier Options for My Product Type?
From oxygen-sensitive meats to moisture-sensitive pharmaceuticals, each product requires different protection. A top-tier non forming film supplier should offer a variety of high barrier options, such as EVOH, nylon, or metallized layers, to preserve freshness and shelf life.
3. How Fast Are Lead Times and Whatโs Your Minimum Order?
Switching suppliers shouldn’t slow down your operations. Ensure the vendor can deliver non forming film with lead times that match your replenishment cycles, and verify whether they require large MOQ commitments. At Sunrise Packaging Films, we offer flexible quantities and fast domestic delivery.
4. Do You Offer Technical Support and Packaging Troubleshooting?
A responsive supplier can help you reduce downtime and solve performance issues. Ask if the vendor offers support like line audits, troubleshooting, and even free failed packaging reviews โ services that are standard with Sunrise Packaging Films.
5. Is the Film FDA-Compliant and Suitable for Food Contact?
For food and medical packaging, safety and compliance are non-negotiable. Be sure to confirm that all materials meet regulatory standards like FDA 21 CFR requirements for food contact. Ask for documentation and material data sheets before placing an order.
