Our 1kilo side gusset pouch with valve is engineered with multi-layer high-barrier materials like PET/AL/PE or MOPP/VMPET/PE, offering complete protection against moisture, oxygen, and light. With a thickness range of 120–160 microns, it supports heavy loads without deformation. The integrated one-way valve operates at 2–8 mbar opening pressure, releasing CO₂ from freshly roasted beans while keeping oxygen out. Backed by 25 years of manufacturing expertise, 7 printing lines, and certifications including FDA, BRC, and ISO 9001, we deliver quality you can trust with lead times as short as 15–20 days.



The best protection for your goods. Our pouches are made with advanced multi-layer lamination that keeps oxygen, water vapor, and UV light out. This will keep your dried foods, specialty teas, or coffee beans fresh for months.
You get proven longer shelf life. Your customers get the full taste and aroma that you intended.
Days after packaging, freshly roasted coffee releases CO2. Your pouch can swell or even burst if it doesn't have enough gas release.
This issue can be fixed with our one-way valve. It lets gases inside leave but keeps air from outside coming in. No swelling. No loss of flavor. Just perfect integrity in the packaging.
When the side gussets are filled, they expand, making a stable box-like shape. This design makes the most of the space on the front, back, and side panels for your logo.
Your pouch sits upright on shelves. It's simple to load, stack, and ship. It saves room and looks great while showing off your brand.

Concerned about sustainability? We offer 100% recyclable mono-material PP or PE versions that meet circular economy standards.
Our production uses imported RTO exhaust gas treatment technology, reducing environmental impact while maintaining top quality.

We don't compromise on quality. Every batch undergoes rigorous testing:
Valve Functionality Test – Vacuum method ensures one-way airflow with zero backflow.
Burst Pressure Test – Verifies side gusset seal strength under full 1kg load stress.
Barrier Performance Analysis – Measures Oxygen Transmission Rate (OTR) and Water Vapor Transmission Rate (WVTR) to confirm protection levels.
Heat Seal Strength Testing – To prevent bottom-seal failure during handling.
Drop Testing – Simulates real-world logistics by dropping filled pouches from 1.5 meters.
These tests guarantee your products arrive in perfect condition, every time.

The 1kilo side gusset pouch with valve is the industry standard for wholesale coffee bean distribution. After roasting, beans emit significant CO₂ volumes. Our valve prevents pouch bursting while locking in peak freshness and aroma.
Perfect for roasteries serving cafés, retailers, and online customers.
Organic kibble and protein-rich treats need moisture protection and convenient dispensing. The side gussets allow easy pouring, while the valve prevents the bloating during palletization and transport.
Your pet food brand stands out with professional, durable packaging.
Moisture-sensitive chemicals, nutritional supplements, and specialty ingredients require hermetic sealing. Our pouch maintains integrity even during high-altitude shipping or in climate-controlled logistics environments.

This generally means the valve is working right, letting the CO2 out of your freshly roasted coffee.
Of course. To keep the layers from delaminating, we use an inner PE layer that is very resistant to oil. Your nuts, snacks, or oily coffee beans stay safely packed.
Internal valves look better and are safer from mechanical damage while being shipped. For 1 kg sizes, internal valves are the professional standard.
Standard laminates with more than one layer can't be recycled. We do, however, have versions made of mono-material PP or PE that are designed to work with recycling programs and the circular economy.
The temperature range for sealing is usually between 160°C and 190°C, but it depends on the thickness. We suggest a dwell of 1.5 seconds for 150-micron structures to get the best seal strength.
