Skin Pack vs. MAP: Choosing the Right Tray Sealing Technology for Premium Proteins

소개

High-end protein and fresh seafood are rapidly growing segments in the food market, and consumers’ demand for their high quality, nutritional value, and safety continues to rise. For these high-value products, packaging is not only a protective layer but also a key factor in preserving freshness, enhancing shelf attractiveness, and maintaining product integrity.

Two mainstream pallet sealing technologies dominate the high-end protein packaging market: tray skin packaging and modified atmosphere packaging (MAP). As a trustworthy manufacturer of packaging machinery, Hualian provides a skin pack tray sealer. The MAP tray sealer solution precisely matches the unique needs of high-end protein producers.

 

Why Packaging Technology Matters for Premium Proteins

High-end protein is priced higher due to its superior quality, compliance with production standards, and high nutritional value. Therefore, packaging plays a key role in protecting this investment and meeting consumer expectations:

Preservation requirements: High-end meat is very prone to spoilage, and it needs to be packaged to inhibit the growth of microorganisms, oxidation, and water loss, thereby extending the shelf life.

Shelf appeal: Consumers judge the quality of high-end protein by appearance – the packaging needs to show the color, texture, and marble pattern of the product while maintaining visual appeal.

Product protection: Delicate meats, seafood, and poultry need to be packaged to prevent physical damage during transportation and storage.

Food safety: Packaging should serve as a pollution barrier to ensure compliance with HACCP, FDA, and other food safety regulations.

Brand differentiation: High-quality packaging can strengthen the product’s high-end positioning and differentiate it from ordinary products.

Hualian‘s tray packaging machine solution – including vacuum tray sealer and MAP sealing machine – accurately meets these core needs to ensure that high-end protein is delivered to consumers in the best condition.

 

What Is Skin Pack Packaging?

Tray skin packaging (commonly abbreviated as skin packaging) is a packaging method based on vacuum technology, which uses a thin and elastic film to closely adhere to the shape of the product and the tray. Its working principle is as follows:

• Place the high-end protein on the preformed tray (preformed tray sealing);
• Heating the transparent film and covering it on the surface of the product and the tray;
• Through the vacuum tray sealing machine, the air in the packaging is sucked out, the film shrinks and tightly adheres to the product and tray, forming a sealed packaging.

Hualian‘s table-type skin vacuum tray sealer is designed for small and medium batch production. It can precisely control the vacuum degree and film temperature, ensuring that every body packaging is perfectly matched.

The core advantages of body packaging for high-end protein include:

Superior preservation: Prevents air contact, reduces oxidation and microbial growth, and extends shelf life by 2-3 times compared to traditional packaging;

Enhance product visibility: Close to the film can clearly show the natural color, texture, and marble pattern of the product, enhancing the willingness of consumers to buy;

Stable protection: The film is like a “second skin”, preventing the product from moving and avoiding physical damage during transportation;

Anti-leakage performance: The sealing design can prevent the leakage of meat juice, keep the packaging clean, and maintain product quality.

 

 

What Is MAP?

수정 된 대기 포장 (지도) is a packaging technology that replaces the air in the packaging with a customized gas mixture to extend the shelf life and maintain the quality of the product. For high-end protein, the gas mixture usually includes:

• Carbon dioxide (CO₂): Inhibits the growth of bacteria and fungi;
• Nitrogen (N₂): Replaces oxygen to prevent oxidation, while maintaining the shape of the packaging as a filling gas;
• Oxygen (O₂): Maintain the red color of fresh meat (beef and lamb usually contain 20-30 percent oxygen).

Hualian‘s automatic compact MAP thermoforming vacuum packaging machine integrates a MAP tray sealing machine with thermoforming capabilities, enabling high-speed production and precise gas ratio control. The core advantages of gas-tight packaging for high-end protein include:

Extended shelf life: Customized gas mixtures slow down the rate of deterioration, and the shelf life is 3-5 times longer than that of air packaging;

Maintain color: Maintain the attractive red color of fresh meat, which is crucial for consumer purchasing decisions;

Flexible: By adjusting the gas ratio, it can be adapted to different types of high-end protein (beef, chicken, seafood, etc.);

Cost-effective: Suitable for mass production, and in some cases, the processing speed is better than that of in-mold packaging.

 

 

5 Key Differences between Skin Pack and MAP

저장 수명

Airtight packaging provides a longer shelf life for high-end proteins, suitable for manufacturers with extensive distribution networks or retailers with longer inventory turnover periods. While in-mold packaging can significantly extend shelf life, it is more suitable for local distribution or products with shorter market cycles.

Product Appearance & Consumer Appeal

The close packaging of the close film presents the texture of “cutting and wrapping at present”, highlighting the product quality and marble pattern, which is particularly attractive to high-end steak and barbecue. The loose film of the modified atmosphere packaging can maintain the color of the product, but it is difficult to fully display the texture details.

Leak Resistance & Product Protection

The sealing design of the body-sealing packaging and the characteristics of the film adhesion make it extremely leak-proof, which can avoid the leakage of meat juice, damaging the packaging and reducing consumer trust. The loose film of the modified atmosphere packaging may cause slight leakage in the juicy meat.

 

Production Speed & Cost Efficiency

Airtight packaging is more suitable for large-scale production, processing speed is faster, and the unit cost of large-scale orders is lower. Sealed packaging is suitable for small and medium-sized batch production, and high unit costs are exchanged for high-end presentation effects.

Sustainability Considerations

Body packaging does not need to reserve gas space, uses less plastic, and is the preferred choice of eco-friendly brands. Modified atmosphere packaging requires additional gas, and larger packaging may increase the use of plastic, but the environmental impact can be reduced by using recyclable film and environmentally friendly gas.

 

Which Tray Sealing Technology Is Right for Your Premium Proteins?

The choice between in-mold packaging and modified atmosphere packaging depends on your specific product, production scale, distribution network, and market positioning. The following guidelines are for your reference:

Scenarios suitable for choosing close-fitting packaging:

• Prioritize high-end product presentation, hoping to highlight texture and marble patterns;
• The product has a medium to short shelf life (7-14 days) or adopts a local distribution model.
• Leakage prevention and product protection are crucial (e.g., juicy meat, seafood);
• To pursue more sustainable packaging solutions and reduce the use of plastic.
• For small and medium-sized production enterprises, Hualian’s desktop vacuum tray sealing machine is an ideal choice.

Scenarios suitable for choosing gas-tight packaging:

• Need to extend shelf life (14-30 days) for national or international distribution;
• Color retention is the primary requirement (e.g., fresh beef, lamb);
• There is a large-scale production requirement (more than 30 plates per minute);
• I hope to reduce packaging costs for large orders;
• It needs to be flexible to adapt to different types of protein products (Hualian’s CO2 tray sealing machine can customize the gas ratio).
