Hongyuan Mass-Produces 16mm & 22mm Spout Caps Simultaneously — Professional Dispensing Solutions for Doypack with Spout
Driven by the trends of concentration, portability, and sustainable packaging, plastic doypacks have become the mainstream packaging format for laundry detergents, fabric softeners, disinfectants, shampoos, lotions, and even cosmetics.

Doypack for shampoo & lotion
Doypack for cosmetics
As a globally reliable packaging plastic supplier, we provide high-compatibility, high-reliability, and high-automation custom doypack dispensing solutions for daily chemical, personal care, and home cleaning brands.
Why Two Spout Sizes? Hongyuan’s Precise Matching for Your Needs
Core Structural Advantages
✅ Leak-Proof MechanismEquipped with a precision-sealed structure to ensure zero leakage when not in use, keeping the pouch clean and extending product shelf life.
✅ User-Friendly DesignErgonomically designed for easy gripping and twisting; enables smooth dispensing without clogging or splashing, supporting one-handed operation for daily convenience.
✅ Accurate Metering ControlOptimized flow channel design delivers stable and controllable liquid output, avoiding waste and ensuring consistent dosage with every use.
Chemical Resistance Performance
Laundry detergents, hand soaps, disinfectants, and similar products often contain acidic or alkaline active ingredients. Hongyuan’s spout caps are made of food-grade PE (polyethylene) or PP (polypropylene), featuring excellent acid and alkali resistance. They will not swell, deform, or corrode even after long-term contact with cleaning agents.
Material Safety & Sustainability
All spout caps are manufactured using food-grade virgin materials, BPA-free, odorless, and safe for skin contact.
Supports the development of recyclable doypack compatibility solutions (mono-material compatible).
The precise dispensing design itself is a form of "green innovation" — reducing overuse and lowering carbon footprint.
Common Issues with Low-Quality Spouts (Fully Addressed by Hongyuan)
❌ Blending recycled materials → Prone to brittleness, odor, and leaching of harmful substances.
❌ Poor dimensional tolerance (>±0.3mm) → Loose caps or inability to fasten securely.
❌ Uneven heat-sealing surfaces → Automatic sealing failures and frequent production line shutdowns.
❌ Lack of chemical compatibility testing → Spout swelling and leakage after long-term storage.
