Vacuum Packing Bags
When a pack is part of your export or production routine, a clear specification matters more than a familiar-looking bag. Use this guide to discuss vacuum packing bags with PackPoly Pakistan for Karachi and Pakistan enquiries. Start with the product going inside and the packing equipment, then distinguish the material, bag construction and intended use.
Two distinct vacuum-packing enquiries
PET/PE laminated vacuum bags
PET/PE describes a laminate combining PET and PE layers, rather than a plain LDPE bag. Ordering finished bags? Specify their dimensions, opening and sealing requirements separately from PET/PE laminated rollstock. Tell us about the contents and equipment so the proposed grade and format can be confirmed for your application.
Special-grade blue food-export bags
Ask about special-grade blue bags for vacuum packing food products for export. The food goes inside the bag, is vacuum packed and then exported. This is a separate application from ordinary coloured or garbage bags. Describe the blue grade you currently use, if known, and your packing process; the material, food-contact requirements and machine suitability will need confirmation with the quote.
Describe the pack, not just the colour
For either enquiry, send the details that define the job:
- The product and whether it will directly touch the bag.
- Usable bag width and length in inches, plus required thickness in micron if known.
- Your vacuum equipment make/model and sealing arrangement.
- Finished bags or rollstock, opening position and any requested three-side-seal construction.
- Storage or handling conditions, plain or printed requirements, quantity in kg and delivery city.
For seam layout and usable measurements, see the three-side-seal bag guide. The construction does not establish the laminate or performance. Tell us if the bag will touch food and we will confirm a suitable grade. Confirm the exact grade, format and equipment suitability for your application before agreeing the order.
Rates and minimum order
Standard stock: minimum 25 kg. Printed bags or custom-size requests: minimum 200 kg. Ask which basis applies to the proposed bag and specification; this page does not promise every vacuum format as standard stock. Rates are on request.
You can request a “1 kg price” as the per-kg rate without changing the minimum order. No numeric vacuum-bag rate or universal performance claim is stated here.
Choose the right enquiry route
If vacuum packing is not needed, compare LDPE bottom-seal bags and LDPE side-seal bags. A zip-lock closure is a separate feature, not evidence of vacuum suitability. See the Karachi packaging supplier guide for other formats.
Take pride in a pack chosen for the actual job. Start with a clear brief, and ask the questions that matter to your product.
