Stand-Up Pouch Industry Evolution: New Applications Drive Growth
- Guangdong Kody Packaging supplies spout pouches, bag-in-box (BIB), stand-up pouches with taps, and laminated roll film to food, personal care, and liquid packaging customers.
- The global colostrum collection bag market was valued at US$145 million in 2024 and is projected to reach US$298 million by 2033 at an 8.4% CAGR.
- Farm case studies show that pre-freezing double-sealed 4-liter upright veterinary bags at -18°C keeps colostrum quality stable for up to one year, and slow warm-water thawing requires unimpeded heat transfer.
- In July 2025, the China-Europe Economic and Technological Cooperation Association approved and released its Test Specifications for Explosion-Proof and Leak-Proof Breast Milk Storage Bags, and the China Industry-University-Research Cooperation Promotion Association issued T/CI 622-2024, while colostrum-specific upright bags prioritize safety, leak prevention, and resistance to temperatures as low as -20°C.
- Multiple U.S. states are introducing EPR legislation for packaging, and China is implementing its Guidelines for Recyclable and Renewable Design of Plastics national standard from February 1, 2026, to push recyclability.
Stand-up and spout pouches have long outgrown the kitchen and the refrigerator. Reliable sealing, freeze tolerance and portability are being rediscovered on livestock farms, in cold-chain medical logistics, in pet food and in home storage, where the format increasingly appears as purpose-built versions such as colostrum bags and breast milk storage bags. Guangdong Kody Packaging supplies spout pouches, bag-in-box (BIB), stand-up pouches with taps and laminated roll film to food, personal care and liquid packaging customers.
Livestock: colostrum bags become a new growth pool for stand-up pouches
On dairy farms, the health and survival of newborn calves depend on receiving enough immunoglobulin-rich colostrum within the first few hours of life. To preserve every precious drop, farms are systematically adopting contamination-free, freeze-safe and portable upright colostrum storage bags.
Market research firm Market IntelO reports that the global colostrum collection bag market was valued at $145 million in 2024 and is growing rapidly at a compound annual growth rate (CAGR) of 8.4%, with projections of $298 million by 2033.
Farm case studies show that pre-freezing these durable, double-sealed 4-liter upright bags, designed for veterinary use, at -18°C keeps colostrum quality stable across a storage period of up to one year. Thawed slowly in warm water, the active nutrients are released quickly as long as heat transfer is unimpeded.
Key parameters:
- Format: 4-liter (4L) upright bag, double-sealed, veterinary use
- Freezing: -18°C; storage period of up to one year
- Thawing: slow warm-water thaw, heat transfer must stay unimpeded
Standards and safety: from farm colostrum bags to household breast milk bags
In July 2025, the China-Europe Economic and Technological Cooperation Association approved and released its Test Specifications for Explosion-Proof and Leak-Proof Breast Milk Storage Bags, while the China Industry-University-Research Cooperation Promotion Association issued T/CI 622-2024, Requirements for Home Breast Milk Collection, Storage, and Transportation. Guided by these standards, colostrum-specific upright bags that prioritize safety, leak prevention and resistance to temperatures as low as -20°C are also widely validated in home and hospital settings.
Consumers keep widening the uses of these upright, multi-purpose sealable bags: homemade bagged face mask recipes, compartmentalized storage of painting supplies, sorting snacks on outdoor trips, or simply packing ingredients, adding sauce and heating everything in the microwave.
Eco-design: EPR rules and national standards push recyclability
Combined with disciplined organization, self-sealing soft pouches let anyone build a portable, stand-up toolbox. As multiple U.S. states introduce Extended Producer Responsibility (EPR) legislation for packaging and China implements its Guidelines for Recyclable and Renewable Design of Plastics national standard from February 1, 2026, recycling and eco-friendly design principles are extending from packaging suppliers to the core of every consumer experience.
From a single spout to a bag of colostrum, from a serving of formula to a pot of frozen broth, the stand-up pouch quietly carries the mission of the times, safe packaging and a green future, through specialized innovation inside a universal format.
