Thermoforming Packaging Explained: Vacuum, MAP & Skin Packaging for Food Products
Among thermoforming solutions, vacuum packaging, modified atmosphere packaging (MAP), and skin packaging are the three most widely used formats. While they may look similar at first glance, each serves a different purpose, relies on different material structures, and suits different product behaviors. Understanding these differences helps buyers choose a packaging solution that actually works in real-world distribution.
Understanding Thermoforming Packaging
Thermoforming packaging involves heating flexible plastic films and forming them into cavities that hold products, followed by sealing with top films. Compared with rigid packaging, thermoforming offers better material efficiency, strong sealing performance, and high compatibility with automated packaging lines.
For food manufacturers, thermoforming packaging is widely used in fresh meat packaging, cheese packaging, dairy snacks, and ready-to-eat food packaging, where oxygen control, moisture barrier, and leak prevention are essential.
1. Vacuum Packaging: Reliable Protection for Shelf Life Extension
Vacuum packaging removes air from the package before sealing, significantly reducing oxygen levels. It slows oxidation and microbial growth, making it a reliable choice for products sensitive to spoilage.
LD PACK’s vacuum packaging films are designed for strength, durability, and consistent sealing under vacuum pressure. They offer high puncture resistance, which is especially important for fresh meat and processed meat with sharp edges.
Key Features
- Superior formability for stable thermoforming cavities
- High oxygen barrier to protect product freshness
- Leak-proof heat sealing for secure storage and transport
Practical Benefits
By removing air, vacuum packaging helps:
- Extend shelf life without preservatives
- Maintain the natural appearance of meat and cheese
- Reduce package volume, lowering storage and logistics costs
LD PACK offers standard and custom vacuum packaging structures, including Mono PE and Mono PP recyclable options, helping brands meet sustainability targets without sacrificing performance.
2. Modified Atmosphere Packaging (MAP): Controlled Freshness with Flexibility
Modified Atmosphere Packaging takes a different approach. Instead of removing all air, MAP replaces the internal atmosphere with a carefully balanced gas mixture. This method is particularly useful when product texture, color, or flavor must be preserved.
LD PACK’s MAP packaging films combine high oxygen barrier performance with strong sealing, ensuring the gas composition remains stable throughout shelf life.
Key Features
- High barrier films protect against oxygen, moisture, and contaminants
- Strong sealing integrity during cold storage and transportation
- Optional easy-peel and anti-fog sealants for a better consumer experience
Practical Benefits
- Extends shelf life while preserving taste and texture
- Reduces oxidation and discoloration
- Improves product visibility on retail shelves
LD PACK supports standard and custom MAP film structures, including Mono PE, Mono PP, and Mono PET, allowing brands to balance performance, machinability, and recyclability.
3. Skin Packaging: Premium Appearance with Secure Sealing
Skin packaging, also known as Vacuum Skin Packaging (VSP), is designed to tightly conform the top film around the product, sealing it directly to a rigid or semi-rigid tray. It creates a premium, second-skin effect that enhances product presentation.
LD PACK’s skin packaging films offer excellent vacuum formability and strong oxygen barrier performance. They can seal to PE, PP, or PET trays and are available in both barrier and non-barrier options.
Key Features
- Tight fit to product shape for enhanced shelf appeal
- High oxygen and moisture barrier for extended freshness
- Strong seal integrity with optional easy-peel functionality
Practical Benefits
Compared with traditional trays, skin packaging:
- Minimizes leakage risk
- Uses less material than bulky rigid packaging
- Fully encloses the product for improved hygiene and safety
LD PACK provides custom skin packaging solutions(available in standard and custom structures), including recyclable Mono PE and Mono PP structures, supporting both premium branding and sustainability goals.
Choosing the Right Thermoforming Packaging Solution
There is no single best thermoforming packaging solution. The right choice depends on:
- Product type and sensitivity to oxygen
- Desired shelf life and storage conditions
- Distribution distance and handling requirements
- Sustainability goals and recycling regulations
Vacuum packaging works well for durability and long shelf life. MAP packaging offers flexibility for texture-sensitive foods. Skin packaging delivers premium presentation and strong product protection. Many brands even use different formats for different product lines.

Thermoforming Packaging FAQs
Q: What is thermoforming packaging?
A: Thermoforming packaging is a process where heated plastic films are shaped into trays or cavities and then sealed with a top film.
Q: Why is thermoforming packaging widely used in food packaging?
A: Thermoforming packaging is widely used in food packaging because it offers strong sealing, excellent barrier performance, and efficient material usage, making it ideal for fresh meat packaging, dairy products, and ready-to-eat meals that require longer shelf life and reliable protection.
Q: How do I choose between vacuum packaging, MAP packaging, and skin packaging?
A: The choice depends on your product characteristics and distribution needs. Vacuum packaging is suitable for products that need maximum oxygen removal and long shelf life. MAP packaging is better when maintaining texture, color, and flavor is important. Skin packaging is often chosen for premium products where appearance, leakage prevention, and product security are key.
Q: Which packaging solution offers the longest shelf life?
A: Vacuum packaging and MAP packaging both significantly extend shelf life, but in different ways. Vacuum packaging removes air to slow bacterial growth, while MAP packaging controls the internal gas composition to reduce oxidation. LD PACK can help evaluate your product and recommend the most effective option.
Q: Are LD PACK’s thermoforming packaging materials recyclable?
A: Yes. LD PACK offers sustainable and recyclable options such as Mono PE, Mono PP, and Mono PET structures. These materials are designed to meet performance requirements while supporting recycling goals in different markets.
