How to choose a pouch fitment
Ruihua supplies the spout-cap component — also called a pouch cap, pouch lid or spout fitment — welded onto a flexible pouch, not the pouch film itself. Start with the product application and opening size, then confirm the cap style and pouch sealing process with samples.
Choose by pouch application
Start with food, cosmetics, detergent or a custom-shape requirement.

Narrow the range by the pouch opening and dispensing needs, from 1.2 to 40 mm.

Frequently Asked Questions
Are your materials food-grade?
Yes. Our spout caps are made of food-grade PP and PE, free from optical brighteners and fluorescent agents, and certified to ISO 9001, HACCP, FDA and EU 1935/2004 (TÜV SÜD) for direct food contact. We also hold the National Industrial Product Production License (QS) for food-use plastic packaging and work to our own corporate standard, Q/STRH.
What is your minimum order quantity?
MOQ depends on the model and whether a custom mold is required. Send us your spout diameter, pouch type and target volume and we will advise the MOQ and lead time for your specific item.
Can you develop custom molds?
Yes. We have more than 30 years of in-house spout-mold experience and hold 38 patents. Our process runs Design → Mold → Sample → Mass Production, so we can open a dedicated mold for your pouch and contents.
How large is your production capacity?
We run one of the world’s largest facilities for this product: a 70,000 m² dust-free workshop with more than 130 injection molding machines, which gives us the highest spout-cap capacity globally. Output can be scaled to your schedule.
How long have you been making spout caps?
More than 30 years in spout molds — we are one of the first factories in China to research and manufacture plastic spouts, we hold key spout-cap patents, and several Chinese spout standards including 8.6 mm and 9.6 mm were set by us. Many Chinese factories run molds we designed and built.
Which spout diameters do you offer?
Inner diameters from 1.2 mm to 40 mm across our spout-cap range, covering cosmetic, pharmaceutical, chemical, juice and liquid-food applications, plus low-temperature, anti-choking and flip-top variants.
How do I get samples and a quote?
Send a picture, the spout inner diameter, a drawing if available, and the pouch and liquid type. We provide samples to test, then quote with quantity, color and destination port, and ship on time with clearance documents.
What sizes of plastic spout cap does Ruihua offer?
Our spout-cap range covers inner diameters from 1.2 mm to 40 mm — from micro/cosmetic bores up to large-caliber caps with carry handles. You can browse by category, by exact diameter, or by cap type, and we develop custom sizes on request.
Do you offer custom colors?
Yes. Caps ship white as standard, and colour is matched to your Pantone reference and run for your order — our color masterbatch passes food tests without optical brighteners or fluorescent agents.
