Problems Faced by Stand-Up Pouch Buyers — And Why PET/MetPET/PE Is the Smartest
Standard Structure for Contract Packers
Stand-up pouches have become the preferred
packaging format for food, FMCG, spices, dry fruits, coffee, pet food, home
care, and export items. They look premium, offer better shelf
visibility, reduce logistics cost, and support faster filling—but
they also bring hidden challenges that many contract packers and brand
owners struggle with.
From leakage issues to printing defects,
from poor barrier performance to machine compatibility problems,
the wrong laminate structure can disrupt operations and increase
rejection rates dramatically.
At G T Pack Industries, we work closely with
contract packers, manufacturers, and exporters who depend on stable,
predictable, and high-barrier packaging. Over the years, we have studied
hundreds of pouch failures and found one common truth:
Most problems in stand-up pouches come from using the wrong structure — especially low-barrier PET/PE combinations.
That is why we have standardized PET/MetPET/PE as our recommended structure for the majority of food and FMCG applications. It solves the top pain points faced by contract packers while offering strong visual appeal and dependable performance on high-speed machines.

Problems Faced by Stand-Up Pouch Buyers
1. Leakage, Seal Failure & Weak Sealing Layer
- Poor seal layers, inconsistent PE thickness, or
incorrect sealing windows cause:
- Corner leaks
- Zipper leaks
- Powder leakage during export
- Coffee/dry fruit aroma loss
- Complaints from retail buyers
- A single batch with seal failure can damage a
brand’s trust.
2. Inconsistent Barrier Performance
- Most buyers underestimate moisture and oxygen
sensitivity in:
- Dry fruits, Spices, Coffee, Namkeen, Masala mixes,
Frozen items
- Low-barrier PET/PE structures allow oxygen and
moisture to penetrate—reducing shelf life, crispness, and aroma
retention.
3. Machine Compatibility Issues
- If the pouch laminate is too soft, too stiff, or the
seal layer is incompatible with the filling line:
- The line slows down
- Seals do not form properly
- Gussets don’t open cleanly
- Pouches fall on conveyors
- Rejection rates increase
- This is a direct operational loss for contract
packers.
4. Print Variation & Colour Problems
- PET/PE lacks metallic base support, causing:
- Dull colours
- Washed-out branding
- Visible imperfections
- Weak product shelf impact
- When brands compete on colour and premium feel, this
is unacceptable.
5. Unclear Food Safety Documentation
- Many small converters fail to provide proper
documents such as:
- Food-grade certificates
- Migration test reports
- Laminate specifications
- Batch traceability
- This slows down audits for exporters and large FMCG
buyers.
6. Supply Delays & Unpredictable Lead Times
- Stand-up pouches require multiple production stages.
When converters outsource printing or lamination, delays become
frequent.
- This disrupts contract packing schedules that run on
tight timelines.
# Why G
T Pack Industries Recommends PET/MetPET/PE as the Standard Structure
PET/MetPET/PE is
widely considered the most reliable and performance-driven laminate
for premium stand-up pouches. Here’s why:
1. Superior Barrier Protection
- The MetPET layer provides:
- High oxygen barrier
- High moisture barrier
- UV/light protection
- Aroma retention
- Shelf life stability
2. Stronger, Cleaner Seal Formation
- The PE layer bonds beautifully with heat seal jaws,
giving:
- Zero leakage
- Consistent seals
- High burst strength
- Excellent tolerance on high-speed lines
3. Better Machine Compatibility
- PET + MetPET combination offers stiffness and
body, which helps pouches:
- Stand properly
- Run smoothly on filling lines
- Maintain shape in logistics
- Work well on zipper and non-zipper formats
4. Premium Printing Quality
- The metallic base enhances colours dramatically:
- Higher gloss
- Better opacity
- Sharper colours
- More premium branding
5. Dependable for Both Domestic & Export
Conditions
- MetPET performs better under:
- High temperature
- High humidity
- Long-distance logistics
- Container storage
