Brief: We show the practical steps and results so you can judge suitability quickly. In this video, you'll see a detailed walkthrough of our high-barrier stand-up sauce pouch's advanced laminated structure. Watch as we demonstrate how the PET/VMPET/PE and PET/AL/PE constructions provide superior oxygen, moisture, and light barriers to protect sauce freshness and prevent leaks. Learn how these materials work together to lock in flavor and ensure your product arrives in perfect condition.

FAQs:
  • What are the key differences between the PET/VMPET/PE and PET/AL/PE material structures?
    The PET/VMPET/PE structure uses metallized PET for a cost-effective oxygen and light barrier with metallic sheen, while PET/AL/PE features aluminum foil for absolute barrier protection against oxygen, moisture, light, and aromas, offering maximum product protection and extended shelf life.
  • How does this pouch prevent flavor loss in sauces and condiments?
    The pouch's laminated structure acts as a robust barrier to volatile compounds, effectively locking in the signature aroma and flavor of your product. Whether it's vinegar tang, garlic spice, or soy richness, the pouch ensures the sensory experience is delivered intact from production to consumption.
  • What are the customization options available for these sauce pouches?
    Our sauce pouches are fully customizable in size and shape, including stand-up or flat formats with options for spouts or dippers. They're available in thicknesses from 60 to 150 microns to suit your specific product volume, shelf presence, and user convenience requirements.
