FAQ

One question we hear often from buyers: does the 10L transparent bag in box use a double-layer design? Yes, it does. The inner layer is food-grade plastic that holds the product directly and stays chemically inert, while the outer layer adds mechanical protection and limits light, oxygen and moisture reaching the contents. This article explains how the double-layer structure works, the benefits it brings to olive oil, juice, milk and other beverages, and how it differs from single-layer bags.

Can oil BIB bags with tap be produced in custom shapes? Yes — and this article explains what determines feasibility: film structure, bag-making and spout-sealing processes, and order quantity. Custom shapes strengthen shelf differentiation and brand recognition, but they can also mean longer lead times and higher one-off investment, so sealing reliability must always come first. Guangdong Kody Packaging (KODY PACK) offers custom-shaped spout pouches, bag-in-box and stand-up bags with tap, plus printing and branding. Contact us for samples and a quote.

Colostrum is the first milk a mammal produces after giving birth, packed with antibodies, vitamins and growth factors that newborn calves need for immunity. A colostrum bag is built around that first milking: aluminum foil laminate blocks light, oxygen and moisture so colostrum keeps its quality in the fridge or freezer, while a feeding-tube model connects directly to a tube for controlled, low-mess feeding. KODY PACK supplies aluminum foil colostrum bags with handle, colostrum bags with feeding tube and custom farm calf feeding bags. Contact us for samples.

Choosing the right spout determines how smoothly a stand up spout pouch dispenses, how reliably it seals and how consumers experience it every day. This guide walks through spout selection for stand up spout pouches: matching bore size and flow control to product viscosity and chemical compatibility, flip-top versus twist-off caps, heat-sealed versus snap-on closures, plastic, metal and rubber materials, branding and aesthetics, food-grade regulatory compliance, and balancing cost with quality. Use it to shortlist the right spout pouch spec, then validate with samples before mass production.

How you store an oil BIB bag with tap decides how long the oil stays fresh and whether the tap still works when you need it. This guide walks through choosing a cool, dark, well-ventilated location, keeping bags upright, protecting the tap, checking seams and the tap for leaks, and using food-grade outer containers such as a transparent Bag in Box 10L. It also covers stock rotation so the oldest bags are used first, plus the selection advice KODY PACK gives food, beverage and liquid packaging buyers.

This article explains the common color options for colostrum bags and how to choose between them. Milky white bags offer a clean appearance and enough transparency to check volume and quality, while aluminum foil bags with handles block light and insulate, protecting antibodies and vitamins during long-term storage. Light blue or green bags are also available for batch color-coding. We also cover how storage environment, visibility needs and organization requirements should guide your choice, along with the colostrum bag options our factory can supply.

Cosmetic spout pouch sachets are a practical, hygienic way to pack creams, but only when the pouch, spout and film are matched to the formula. This guide from a spout pouch manufacturer explains the hygiene, portability and cost benefits of sachet packaging, the viscosity and shelf-life limits to watch, and how to choose spout diameter, fill volume, closure type and printing for sample or retail sizes.

Cosmetic spout pouch sachets are sensitive to air, moisture and contamination, so a weak seal quickly turns into leakage, oxidation and microbial growth, and a hit to brand reputation. This article walks through the practical ways to measure sealing integrity: quick on-line visual inspection and bubble testing, non-destructive vacuum decay and ultrasonic testing, and the destructive dye penetration test, plus why sealing checks need to be scheduled and documented.

Choosing a custom farm calf feeding bag comes down to a few essentials: food-grade material that resists tearing and can be cleaned or sanitized, a capacity matched to calf age — roughly 1-2 quarts per feeding for newborns and 3-4 quarts for older calves — and a nipple whose softness and hole size control sucking comfort and choking risk. Wide mouths, handles, folding portability, farm branding and compatibility with existing milk containers matter just as much for daily feeding efficiency.

Spout pouches deliver strong barriers against oxygen, moisture and light, but how long a product stays fresh inside depends on the product itself, the packaging material structure, storage conditions and seal quality. This guide breaks down the key factors that shape spout pouch shelf life and provides practical reference ranges for food and beverages, cosmetics and personal care items, and cleaning supplies, so you can match the right pouch to your product.
