It's a fact—we live in a world where packaging is essential. From the food you eat during Zoom calls to the fancy meals everyone is buying, packaging is essential and has become an art. It affects how the brand is seen, ensures the quality of goods, lowers waste and impacts transportation. But the most important question is: Is vacuum packaging equipment more effective than other ways to pack?
The advancement in packaging can be seen from the modern vacuum machines to the advanced MAP packaging machines we have today. These days, foodservice focuses on making food last longer, keeping it fresh, cutting down on food waste, enhancing safety and, of course, making food look beautiful to the customer.
So get ready, packaging lovers, because we are exploring the world of seals. Let's take a closer look at vacuum sealer packaging machines and compare their advantages, disadvantages and state-of-the-art features to those of modern packaging systems.
This is like comparing a James Bond gadget to a roll of duct tape. Sure, both get the job done, but one does it with flair.
Shrink wrapping involves wrapping a product in plastic film and applying heat to shrink the film snugly around the item. It's like giving your product a tight hug. This technique is commonly used for packaging software boxes, electronics, books, and even food trays.
Cost-efficient for high-volume operations
Enhances product presentation
Adds a layer of tamper-resistance
Lightweight and low waste material
Doesn't significantly improve shelf life
Offers limited protection against bacteria
Not ideal for perishable items
Requires heat tunnel equipment
Vacuum packaging, in contrast, removes air from the package before sealing it shut. No oxygen? No problem. Without oxygen, the growth of aerobic bacteria and mold slows dramatically, making it ideal for preserving food.
Extends shelf life dramatically — up to 3–5 times longer
Preserves original flavor and texture
Reduces oxidation and freezer burn
Saves space with stackable, compact packages
Hygienic and tamper-evident sealing
Enhances food safety by limiting microbial exposure
Vacuum packaging offers superior protection for perishable foods. Whether you're sealing frozen meats, seafood, coffee beans, or grated cheese, vacuum sealer packaging machines deliver consistent quality and long-lasting freshness.
That depends on the application:
For food preservation — Yes, absolutely. Vacuum packaging is unmatched for extending freshness and maintaining product integrity.
For surface wrapping (e.g., boxes, bundles, retail presentation) — No. A heat shrink machine is the better choice, offering tight, clear, professional wrapping that enhances shelf appeal.
MAP replaces the air inside a package with a carefully controlled mix of gases—typically carbon dioxide (CO₂), nitrogen (N₂), and oxygen (O₂). This gas combo is customized to the product's specific preservation needs. Think of it as a luxury VIP suite for your food, often delivered through a MAP packaging machine or a MAP vacuum sealer.
Vacuum Packaging = removes all air
MAP = replaces air with a tailored gas mixture
Fresh produce that needs a specific respiration environment
Red meats requiring oxygen for color retention
Fresh-cut salads
Cured meats
Hard cheeses
Seafood and poultry
It is tools like the MAP packaging machine, MAP vacuum sealer or the hybrid Map Tray Sealer system for proper MAP implementation.
Pro Tip: If you're selling produce that still "breathes" post-harvest, MAP is ideal. If the goods are low in moisture or can tolerate no oxygen, vacuum packaging is the best way to go.
Nitrogen, an inert gas, is used in this approach to substitute the oxygen present in the package. That's the secret behind the crispy texture of your chips. It's like kicking out your irritating housemate (oxygen) so your snacks don't get bothered.
Stops oxidation of fats and oils
Great choice for snack foods like chips and cookies
Maintains product structure and texture
Gentler on delicate products compared to vacuum
Extends shelf life more significantly for perishables
Protects against both moisture and air exposure
Ideal for a wider range of food categories
More compact packaging footprint
For processors focused on long-term storage or cold-chain logistics, vacuum sealer chamber machines provide superior protection. Nitrogen is better when presentation and puffiness are important (like snack bags).
Time to get under the skin—literally.
Skin packaging places a clear plastic film over a product, forming a second skin that contours tightly to the item and its base. This method excels at showcasing high-value items in a shelf-ready format.
Excellent product visibility
Reduced material use vs. clamshells
Good for displaying tools, hardware, or frozen goods
Improved tamper-resistance
Not air-tight
Limited shelf-life extension
Mainly suited for rigid items
Now, combine skin packaging with vacuum tech and you get Vacuum Skin Packaging (VSP)—the best of both worlds. VSP not only conforms to the product for visual appeal but also removes oxygen, drastically extending shelf life.
Vacuum skin packaging machines
Thermoforming packaging machines
High-barrier skin films
Use Case:
Fresh salmon fillets, gourmet steaks, marinated kebabs—VSP keeps these products fresh, juicy, and stunning on the shelf.
Ah, the speed vs. security debate.
Tray sealing involves placing a food product in a preformed tray and sealing it with a plastic film. It's quick, widely used in ready-to-eat meals, and ensures tamper-evidence.
Ideal for high-throughput environments
Attractive and retail-ready packaging via a tray sealer
Offers moderate barrier protection
Doesn't remove air unless combined with vacuum tray sealing machines
Shorter shelf life compared to vacuum packaging equipment
This is where vacuum tray sealing machines enter the scene. These hybrid units combine the speed of tray sealing with the oxygen-sucking power of vacuum packaging. It's a packaging power couple.
High-speed packaging
Extended freshness
Great for pre-packaged meals and deli counters
This isn't a battle—it's a case of different tools for different jobs.
Primary use: Fresh food (meat, fish, poultry)
Key strength: Preserves freshness, flavor, moisture, and extends shelf life
Target industry: Food retail
Packaging type: Airtight, cling-style vacuum seal over product and tray
Primary use: Non-food retail (electronics, tools, medication)
Key strength: Product visibility, theft deterrence, cost-effective for mass non-perishable items
Target industry: Hardware, pharmaceuticals, consumer goods
Packaging type: Plastic dome sealed to cardboard or foil backing
Ask "What am I packaging?"
If it's food: VSP is unbeatable.
If it's electronics or hardware: Blister packaging is your go-to.
It's not about which one is better overall—it's about fitness for purpose.
Now the story is starting to pick up.
Both these processes aim to keep products fresh and look appealing. MAP moderates the gas that fills the package, while VSP gets rid of all the air and sticks to the product like a layer of skin.
Flexible for a variety of food types
Great for fresh produce
No oxygen = lower spoilage risk
Excellent product visibility
Ideal for premium cuts of meat and marinated products
What do you think is your best choice? The answer depends on the product. For products that are very moist and have low respiration, VSP gives the best results. If the product is delicate, MAP is the more effective choice.
Remember peeling back a layer of film on your microwave dinner? That's traditional top sealing.
Involves sealing a tray with a plastic film
Suitable for basic storage and microwavable meals
Doesn't eliminate oxygen
Shorter shelf life
VSP is the next-gen solution. It offers better product stability, longer freshness, and a more premium look.
Improved shelf life
Tamper-evident seal
Better moisture retention
Visual "high-end" appeal
There are different vacuum packaging machines designed for different products, industries and types of packaging. Here are the most frequent types you may need, to help you pick the right one for your business or home.
Chamber vacuum packaging machines enclose the whole package in a sealed chamber. By taking the air out of the inside and outside of the bag, it becomes suitable for liquids, powders and soft foods. It's common to see them in kitchens and plants for food manufacturing with a vacuum sealer chamber for reliable work.
With external vacuum sealers, you only insert the bag's open end into the package to seal it. These are best suited for dry goods or solid products and are often bought for homes because they are both simple and inexpensive.
Automatic vacuum packaging machines, including thermoforming systems and MAP tray sealers, are used in food processing to extend shelf life. They differ from automatic shrink wrappers, which do not vacuum seal or preserve freshness. Shrink wrappers are for non-perishable retail packaging only, not suitable for food preservation applications.
Handheld vacuum sealers are compact and portable—perfect for quick sealing jobs on the go. Great for travelers or casual home use, they're handy for resealing snack bags or small containers.
A double chamber vacuum sealer has two chambers, allowing one package to be sealed while another is being prepared. This setup is ideal for busy production lines demanding speed and efficiency.
Skin packaging machines vacuum seal the product tightly against a specially designed plastic film, creating a "second skin." This vacuum skin packaging method is perfect for preserving and displaying fresh meat, cheese, or produce. Often seen in retail settings, skin packaging boosts shelf appeal while maintaining airtight protection.
Other common tools you might consider include a MAP tray sealer—especially relevant when dealing with Modified Atmosphere Packaging (MAP). If you're working with heat-sensitive products, a heat shrink wrapping machine or general shrink wrapping solution might suit your needs better.
Each type offers unique benefits depending on your packaging goals, product type, and scale of operation. Whether you're preserving homemade meals or running a large factory, there's a vacuum packaging machine, tray sealing machine, or MAP tray sealer designed to make your life easier and your products last longer.
Is using a vacuum better for packaging than other techniques? Absolutely, if you work in food and are worried about keeping your products fresh, safe and attractive.
MAP (Modified Atmosphere Packaging) and nitrogen flushing are advanced vacuum-based technologies often categorized under broad vacuum packaging. Unlike shrink wrapping and standard sealing, these methods—especially MAP—are highly effective at preserving freshness, safety, and extending shelf life, making them ideal for food products.
Thanks to vacuum tray sealing machines, chamber vacuum sealers and vacuum skin packaging systems, you can save the whole experience of a meal.
