Vacuum Packaging vs. Tray Sealing: Understanding Henkelman and Enterpack

Food businesses have more packaging options than ever, but choosing the right packaging method starts with understanding what you need the packaging to accomplish.

Two technologies commonly used in professional food operations are vacuum packaging and tray sealing. While both can help businesses package food efficiently and consistently, they serve different purposes.

Henkelman vacuum packaging equipment and Enterpack tray sealing equipment are good examples of these two approaches.

Understanding the difference can help restaurants, grocery stores, caterers, meal-prep companies, food processors, butcher shops, and other food businesses determine which process—or combination of processes—makes the most sense for their operation.

Vacuum Packaging and Tray Sealing Solve Different Problems

At a high level, the biggest difference is how the food is packaged.

Vacuum packaging removes air from around the product before sealing it.

Tray sealing places food in a rigid tray and seals the tray with a film.

Neither approach is automatically better than the other. The right choice depends on the food being packaged, how it will be stored, how it will be transported, and how the finished product will be presented to the customer.

That is why understanding the differences is important before choosing equipment, accessories, or consumables.

What Is Vacuum Packaging?

Vacuum packaging removes air from a package before creating a seal.

Henkelman manufactures professional vacuum packaging equipment used across foodservice, retail, catering, food processing, meat, fish, and other applications. Vacuum packaging can be used to help protect products, support shelf-life goals, reduce food waste, and organize food production and storage.

For example, a commercial kitchen may use vacuum packaging to:

  • Portion ingredients
  • Package meat and fish
  • Prepare products for sous-vide cooking
  • Store prepared ingredients
  • Protect food during refrigerated or frozen storage
  • Reduce exposure to air
  • Prepare products in advance

Vacuum packaging can be particularly useful when removing air from around the product is an important part of the packaging process.

Common Henkelman Components and Accessories

A vacuum packaging system also requires components and consumables that need to be maintained or replaced over time.

Depending on the machine and application, these may include:

For example, Invacus Parts offers Henkelman service kits for different machine and pump configurations. Some kits include components such as a lid gasket, oil, Teflon tape, silicone profile, and seal wires. Browse Henkelman service kits to find the appropriate option for your equipment.

Keeping the correct replacement components available can help reduce unnecessary downtime and make routine maintenance easier.

What Is Tray Sealing?

Tray sealing takes a different approach.

Food is placed into a rigid tray, and a sealing film is applied over the top of the tray. The film is heat sealed around the tray's perimeter to create a finished package.

Enterpack tray sealing systems are designed around this type of packaging process, using interchangeable heater sets along with different tray formats and sealing films.

This allows businesses to use different packaging configurations for different products and applications.

Tray sealing can be particularly useful for:

  • Prepared meals
  • Grab-and-go foods
  • Ready-to-eat meals
  • Catering portions
  • Deli products
  • Meal-prep products
  • Multi-compartment meals
  • Refrigerated prepared foods

The finished tray can also provide a consistent and professional presentation for products being sold directly to customers.

Enterpack Components and Consumables

The equipment is only one part of a tray sealing system. The correct Enterpack heater set, tray, and sealing film need to work together for the intended application.

Invacus Parts currently offers Enterpack products including:

Because Enterpack heater sets are designed for specific tray configurations, compatibility is an important consideration when ordering replacement or additional components.

Henkelman vs. Enterpack: What's the Difference?

The easiest way to understand the difference is to consider the primary purpose of each technology.

Henkelman Vacuum Packaging Enterpack Tray Sealing
Primary process Removes air before sealing Heat seals film to a rigid tray
Packaging format Vacuum bags and compatible packaging Rigid trays and sealing film
Air removal Central to the process Not the primary purpose
Prepared foods Yes Yes
Portioning Yes Yes
Grab-and-go presentation Depends on packaging format Strong fit
Multi-compartment meals Depends on packaging format Available with compatible trays
Common consumables Vacuum pump oil, filters, seal components Trays, sealing film, heater sets

The important takeaway is that these systems aren't necessarily competing for the same application.

They can serve different roles within the same food operation.

When Does Vacuum Packaging Make More Sense?

Vacuum packaging may be the better choice when removing air from around the food is important.

For example, a food producer may want to portion raw meat and vacuum package it for storage. A restaurant may vacuum package ingredients for sous-vide preparation. A catering operation may vacuum package ingredients or prepared products for organized refrigerated storage.

In these situations, the vacuum process itself is an important part of the packaging strategy.

The packaging format may also be more compact and flexible for certain products.

When Does Tray Sealing Make More Sense?

Tray sealing can be a strong option when the food needs to be presented as a finished tray-based product.

Consider a grocery store preparing hundreds of grab-and-go meals.

The food can be portioned into trays, sealed with film, labeled, refrigerated, and placed into a display case.

A meal-prep company may use different tray configurations for different meal plans.

A restaurant may package prepared meals or family-style portions for customers to take home.

A caterer may package individually portioned meals for an event.

In each of these situations, the tray itself becomes part of the finished product.

Businesses interested in exploring the available formats can browse Enterpack trays, heater sets, and sealing film at Invacus Parts.

What About Businesses That Need Both?

This is where the comparison becomes especially useful.

A food business doesn't necessarily have to choose between vacuum packaging and tray sealing.

It may find that each technology serves a different purpose.

For example, a commercial kitchen could use vacuum packaging for:

Ingredient preparation and storage

while using tray sealing for:

Finished prepared meals and grab-and-go products.

This gives the business flexibility to choose the packaging process based on the product rather than trying to force every food item into the same packaging format.

As a food business grows, that flexibility can become increasingly valuable.

A restaurant might add prepared meals.

A butcher shop might introduce ready-to-cook dinners.

A grocery store might expand its deli and grab-and-go selection.

A meal-prep company might increase production from dozens of meals per day to hundreds.

Different products may require different packaging approaches.

The Right Packaging Process Depends on the Product

There isn't one packaging technology that is ideal for every food product.

Instead, consider questions such as:

  • Does the product benefit from air removal?
  • Is the product being stored or sold as a finished meal?
  • Does presentation matter?
  • Does the product need to be portioned?
  • Does the business need multiple tray sizes or configurations?
  • Will the product be displayed for grab-and-go sales?
  • How much packaging volume does the operation handle?
  • What packaging consumables will the operation need?
  • How frequently will equipment require maintenance or replacement components?

Answering these questions can make it easier to determine which packaging process fits the application.

Choosing the Right Accessories and Consumables

The equipment is only part of a successful packaging operation.

Both vacuum packaging and tray sealing systems rely on the correct components and consumables.

For Henkelman equipment, proper maintenance may involve items such as vacuum pump oil, filters, gaskets, seal components, and service kits.

For Enterpack equipment, the packaging configuration can depend on selecting the appropriate heater set, tray, and sealing film.

This is particularly important with tray sealing because the heater set, tray, and film need to work together as a system.

Using the correct combination can help ensure that the equipment is configured for the intended packaging application.

Why Equipment Compatibility Matters

One of the most common mistakes businesses can make when purchasing packaging supplies is assuming that every accessory or consumable will work with every machine.

That isn't always the case.

Different machines and configurations can require specific components.

With Enterpack, for example, different heater sets are designed for specific tray formats. Different trays may also require compatible sealing film.

Understanding the equipment configuration before ordering replacement or additional supplies can help prevent purchasing the wrong component.

Invacus Parts provides Enterpack trays, heater sets, and sealing films as well as a broad selection of Henkelman OEM parts and accessories.

Supporting Your Packaging Equipment

Whether a business relies on vacuum packaging, tray sealing, or both, equipment maintenance is an important part of keeping production moving.

Small components can wear over time. Consumables need to be replenished. Sealing surfaces need to remain clean and properly maintained. Vacuum systems require appropriate maintenance of their pumps and related components.

For Henkelman operators, Invacus Parts also provides resources covering common equipment issues. If you're troubleshooting a vacuum sealer, see our guide on how to fix common Henkelman vacuum sealer problems.

Having the right parts and supplies available before they are urgently needed can help reduce unexpected interruptions.

Finding the Right Packaging Solution for Your Operation

Henkelman vacuum packaging systems and Enterpack tray sealing systems approach food packaging from different directions.

Vacuum packaging is centered around removing air and creating a sealed package around the product.

Tray sealing is centered around placing food in a rigid tray and creating a sealed, presentable package with film.

For some businesses, one approach may be all they need.

For others, using both can provide greater flexibility across different products and stages of production.

The important thing is to start with the application.

What are you packaging? How are you storing it? How will the customer receive it? And what does your production process need to accomplish?

Once those questions are answered, choosing the appropriate equipment, parts, trays, films, and accessories becomes much easier.
