Thermoform Modified Atmosphere Packaging

Food packaging methods have gone through significant evolution since vacuum and MAP packaging became very popular in the late 1950s. While vacuum sealing helps to increase shelf life, some food items saw changes in their appearance and texture. This called for advanced modes of packaging. Thermoform modified atmosphere packaging became a preferred option as it replaces oxygen with a special gas mix to maintain the freshness, quality, and appearance of the food. Now, this technology is widely used across the food industry to receive more hygienic and efficient packaging. As one of the most dependable packaging machinery suppliers, Cehuma delivers the best packaging solutions made to help businesses improve their food production and packaging performance.

Working of a Thermoform Modified Atmosphere Packaging Machine

A modified atmosphere packaging machine is an advanced packaging system that can extend the shelf life of food. It does this by replacing the air inside with a controlled mixture of gases, often carbon dioxide and nitrogen. MAP preserves the colour, texture, and freshness of the food and also prevents oxidation and microbial growth, unlike standard vacuum packaging, which removes all of the air. The thermoform system forms the package from roll stock into which a product is placed. Then a vacuum is created, and a specialised gas mixture is pushed inside. At last, the package is sealed properly to make sure the quality of the product lasts for a long time.

Reasons To Use A Thermoform MAP Machine

Maintaining freshness to avoid spoilage is really important for food manufacturers, as it is needed for customer satisfaction and good sales. A MAP packaging machine is designed to provide dependable food shelf life extension by creating the best packaging atmosphere to protect the food from production to sales.

  • Increases the shelf life of food items and keeps them fresh
  • Maintains the color, texture, and appearance for better visual appeal
  • Cuts down food waste as quality is preserved during storage and transportation
  • Produces strong seals, eliminating leaks and contamination
  • Delivers fast and automated packing performance
  • Improves operating efficiency and lowers loss

For example, meat that is packed using MAP will have its natural red colour for a longer time than one packed by a convection vacuum system, making it more appealing to buyers.

Industries That Benefit From This

Thermoform MAP machines are commonly used in industries where freshness, hygiene, and lifespan are very important.

  • Meat and Poultry: The meat packaging machine can maintain the color, texture, appearance, and freshness without spoilage.
  • Dairy: Dairy products such as cheese, yogurt, butter, etc. can be protected from deterioration with a dairy packaging machine.
  • Seafood: The storage life and freshness of fish and shellfish can be maintained with the system.
  • Bakery: Keep baked goods fresh along with their texture and flavor.
  • Fresh produce: Slow down the natural aging process of fruits and vegetables.
  • Dried fruits and nuts: Preserve the crispness and taste with MAP packaging.
  • Medical products: Secure, hygienic, and quality packaging for medical kits and other healthcare supplies.

A supermarket that sells chicken, sliced cheese, and fresh salad can use a single thermoformer MAP machine to pack it individually with the right mixture of gas. This keeps the products fresh for a longer time and reduces the chance of spoilage during movement to make sure that the customers receive products in the best condition.

Key Technical Specifications to Consider

  • Production Capacity: 5–12 cycles per minute.
  • Forming Depth: 60–150 mm for various product sizes.
  • Web Width: 180–600 mm for flexible packaging formats.
  • Energy Consumption: Efficient operation with 8–38 kW power usage.
  • Air Pressure: Requires 6–8 bar for consistent gas flushing packaging performance.
  • Cooling Requirements: Cooling water temperature of 10–16°C for consistent operation.

How to Choose the Right Thermoform MAP Machine

It is important to choose a thermoforming packaging machine that is right for the current production needs and future business plans. Keep these factors in mind:

  • Production Volume: The machine capacity must be equal to the daily output.
  • Product Type: The model must match the products.
  • Packaging Format: Make sure that the machine is compatible with trays, pouches, and high-barrier packaging films.
  • Automation Level: The selected level of automation must be efficient and reduce labor.
  • Future Expansion: Invest in machinery that can grow as production grows.

Maintenance Tips for Long-Term Performance

Regular maintenance is necessary to keep the food packaging equipment working efficiently and to reduce chances of unforeseen downtime. Follow these best practices:

  • Clean the machine every day to maintain cleanliness and remove product residue.
  • Inspect the sealing components on a regular basis to keep the packaging airtight.
  • Check the gas flushing system for accurate gas delivery.
  • Have a preventive maintenance schedule to inspect moving parts and to change ones that are worn.

A well-maintained machine will deliver consistent and dependable performance. Not just that, it'll also extend the lifespan of equipment and make sure the packaging quality is excellent for every production cycle.
