Frequently Asked Questions about Vacuum-Sealed Bags

  • Depending on the need for durability and shelf life, different thicknesses should be considered.
  • The greater the thickness, the higher the resistance to environmental factors and oxygen transmission, which in turn increases shelf life.
  • Our standard thickness options are 65, 70, and 100 microns.
  • For larger quantities of product to be packaged, it is also advisable to use a thicker material.

It is recommended to use a heat sealer or a chamber vacuum machine, ensuring that the width of the sealing bar is greater than the width of the bag.

No, our bags are not suitable for home vacuum machines (such as FoodSaver). We recommend using chamber vacuum machines for best results.

THREE SIDE SEAL BAG

The three-side seal bag is a widely used packaging type in the food industry due to its durability, airtightness, and preservation capabilities.

Its design and functionality make it ideal for protecting food during storage and transportation.

Design of the Three-Side Seal Bag

  1. Materials:
    • Typically made from multi-layer plastic films (such as polyethylene, polypropylene, or metallized sheets) that provide barriers against moisture, oxygen, and external contaminants.
    • In some cases, materials with special properties are used, such as high-temperature resistance or compatibility with freezing.
  2. Structure:
    • Three seals: The bag is hermetically sealed on three sides, leaving one side open for filling with the product. Once filled, the fourth side is sealed using heat or pressure.
  3. Sealing Methods:
    • Thermal sealing: Uses sealing machines that apply heat and pressure.
    • Vacuum sealing: Removes air before sealing, extending the product's shelf life.

Advantages for the Food Industry:

  • Hygiene and safety: Airtightness reduces the risk of contamination.
  • Longer shelf life: Maintains the food's properties for a longer period.
  • Logistical optimization: Its compact design saves space during storage and transportation.
  • Sustainability: Many manufacturers offer recyclable or biodegradable options.

The three-side seal bag is an efficient and reliable solution for safely packaging food, preserving its quality, and meeting industry standards.

Advantages of the Three-Side Seal Bag

    Food Protection

    • The materials and seals prevent the entry of air, moisture, and microorganisms that could spoil the product.
    • This is especially crucial for perishable items like meats, cheeses, or frozen products.

    Freshness Preservation

    • In vacuum-sealed bags, air removal reduces oxidation and bacterial growth, keeping food fresh for longer periods.

    Versatility

    • Suitable for solid, liquid, or powdered foods.
    • Allows for custom printing to include product information, branding, and attractive designs.

    Ease of Use in Industrial Processes

    • Compatible with automatic packaging machines.
