Explore our top-performing flexible packaging solutions crafted for coffee, tea, matcha, and specialized retail products.
Matcha (Japanese shade-grown stone-ground green tea, Camellia sinensis) represents one of the most sensitive bio-active botanical powders in the premium beverage market. Unlike whole-leaf tea or roasted coffee beans, fine matcha powder features an exceedingly high surface area-to-mass ratio, rendering it hyper-vulnerable to four primary environmental degradation vectors: photo-oxidation, oxygen absorption, moisture ingress, and thermal degradation.
When high-grade Ceremonial or Culinary matcha is exposed to ambient oxygen or UV light, the vital pigments—specifically chlorophyll a and b—rapidly degrade into brown pheophytin. Concurrently, delicate catechin polyphenols, L-theanine amino acids, and volatile aromatic terpenes suffer irreversible oxidative damage, turning a vibrant emerald-green powder into a dull, bitter brown substance. As a professional wholesale flat bottom matcha bag manufacturer & supplier, YPAK PACKAGING GROUP engineers multi-layer barrier flexible pouches specifically calibrated to eliminate these degradation factors, ensuring shelf-life extension of up to 24 months under standard retail ambient conditions.
Precision engineering of oxygen transmission rates (OTR) and water vapor transmission rates (WVTR) for maximum chlorophyll retention.

Oxygen degrades catechins into quinones, altering taste profiles. Our high-density aluminum foil and metallized PET laminates eliminate gas permeability, retaining authentic umami profile.
Matcha powder is extremely hygroscopic. Water vapor exposure causes micro-clumping and bacterial growth. Our specialized low-density linear polyethylene (LLDPE) seal layers guarantee hermetic heat seals.
Direct exposure to UV wavelengths between 300nm and 700nm degrades bioactive compounds. We incorporate opaque outer film layers and UV-blocking varnishes to keep the powder vibrant green.
Why leading international tea brands are transitioning from traditional tins and Doypacks to 5-panel flat bottom pouches.
Flat bottom bags feature front, back, bottom, and left/right side gussets. This provides five distinct display surfaces for multi-lingual compliance labeling, nutritional tables, origin stories, and artwork without creasing distortion.
Unlike standard stand-up pouches that curve at the base, flat bottom bags rest completely flat on retail shelves and automated filling lines. This structural design prevents tipping during high-speed powder filling operations.
Matcha micro-fine dust can contaminate standard zipper channels. We integrate specialized Front Pocket Zippers and De-dusted Press-to-Close Zippers, allowing consumers easy scoop access while maintaining air-tight resealability.
Global supply chain strength backed by world-class food safety certifications and cutting-edge printing tech.
Founded in 2011, YPAK PACKAGING GROUP operates three state-of-the-art manufacturing facilities strategically located across Hong Kong, Dongguan, and Foshan. As one of China’s premier flexible packaging leaders, YPAK specializes in custom flat bottom pouches, barrier coffee bags, compostable packaging, and high-precision adhesive labeling systems.
Our modern production bases in Foshan and Dongguan are certified to BRCGS Food Safety Grade A and ISO 22000:2018 standards. Every batch of packaging produced in our dust-free cleanrooms strictly adheres to global food contact standards, including US FDA 21 CFR 177.1520, EU Regulation (EU) No 10/2011, and Japan Food Sanitation Law. We fit genuine Swiss WIPF one-way degassing valves as standard option for coffee applications and micro-powder seals for delicate matcha products.
