Tray sealing film generally comes in three practical options. Clear film keeps the food visible, while custom-printed film carries your brand. For frozen or microwave-ready meals, the film is selected around the actual use conditions.
A container sample is ideal. If you do not have one yet, photos, dimensions or the equipment model are enough to start.
PRODUCT RANGE
Tray sealing film generally comes in three types. Clear film shows the food, while custom-printed film carries logos, product names and other information. If the pack will be frozen, microwaved or transported for longer periods, the film is selected around those actual conditions.
Clear film suits ready meals, salads and fresh foods that should remain visible. If you are unsure about the container material, send a photo of the PP, PE or PLA marking on the base together with an actual container for confirmation.
If customers should see the brand as soon as they pick up the pack, the logo, product name and required information can be printed directly on the film.
Food that will be frozen, microwaved, or exposed to sharp edges and pressure needs a different film choice. Share the actual use conditions so suitable films can be tested.
PACKAGING USES
The most useful questions are simple: What goes into the container? How will it be stored? Will customers heat the whole pack? These answers shape the film choice. The four common situations below make it easier to find the right direction.
For ready meals, salads, fresh food and takeaway, three things are usually checked: container material, rim shape and whether the existing tray sealer can run the film.
With soups and oily foods, leakage during transport is the main concern. Liquids and oils can affect the seal, so testing uses the actual food and container.
Frozen packs go through freezing, thawing and distribution. Storage temperature, time and transport conditions are therefore reviewed together.
For meals heated in the container, the container, food, film and heating method all affect the result. A steam vent sticker can also be considered when steam needs to escape.
WHAT IT HELPS YOU DO
Use the actual container and tray sealer to identify a suitable film.
Clear film lets customers see the meal and ingredients.
Place logos, product names and required information directly on the film.
Arrange tests for chilled, frozen, heated and transported packs.
OPTIONAL FUNCTIONS
Storage and heating methods change what the film needs to do. Chilling, freezing, microwave heating, sharp edges and transport pressure can all be included in the test plan.
Each film has different properties. Final suitability is confirmed from tests with the actual container, food and equipment.
START WITH YOUR PRODUCT
A container sample is ideal. Photos, dimensions, food type, storage method, heating method and the current equipment model are also enough to begin.
Final specifications, minimum order quantity and lead time require separate confirmation.
Container size, rim shape and use conditions vary, so film specifications change as well. A sample is needed to confirm width, thickness and required functions.
| Product types | Clear sealing film, custom-printed sealing film, and films for freezing, microwave use and other special needs |
|---|---|
| Containers for evaluation | PP, PE and PLA markings are usually found on the container base. A photo helps start the review, but the actual container is still checked because rim shapes can differ. |
| Applications | Ready meals, soups and hot pot, chilled and frozen food, microwave food packaging, fresh meat and seafood |
| Functional options | Freezing, microwave use, resistance to sharp edges, and reduced entry of air or moisture; actual suitability requires testing |
| Custom printing | Logos, product information and brand layouts, with support for artwork, color, seal area, cutting position and print registration |
| Confirm separately | Film width, thickness, minimum order quantity, lead time and final function combination |
Tell us whether the food contains liquid or oil, how it is stored, heated and transported, and how the pack should open. This helps narrow down which films to test.
A container sample is ideal, but photos, dimensions, food details, storage method or equipment model can also be provided first.
The container, film and equipment are tested together to check seal strength, performance after heating and ease of opening.
After the samples and artwork are approved, film dimensions, printed content and order conditions can be finalized for production.
It may be possible, but testing is required. The container, food, freezing temperature and microwave method all affect whether one film can cover the full process.
Yes, this can be reviewed. Provide the equipment model, current film and container samples so film width, winding direction, registration and machine settings can be checked.
Prepare the logo, brand colors and the text or graphics to be printed. The layout, seal area, cutting position and print registration can then be arranged.
The film has to match the container and equipment. Container size, rim shape and machine settings affect the required width and thickness, so samples are reviewed before a specification is proposed.
After the container, food and equipment details are reviewed, any missing information will be identified.
