At Zhejiang Haoyuan Machinery, we engineer heat patch production line solutions that help manufacturers scale from manual or semi-automatic processes to stable, repeatable automation. This category covers complete and modular systems for producing and packaging warm patches and related products—built to keep output consistent, reduce labor dependency, and support reliable sealing and finished-pack presentation.
Our Heat Patch Production Line range includes equipment for multiple product formats and process needs, such as Automatic Steam Eye Mask Production Line, Automatic Hand Warmer Packaging Machine, Knee Patch Packaging Machine / Auto-Fill Knee Patch Packaging Machine, and specialized units like the Auto-Fill Powder Neck Sticker Machine HY-600CSB. We also provide different feeding structures (single-feed, dual-feed, and double-additive designs) so the line can be configured around your material type, formula handling, and production rhythm.
What is a Heat Patch Production Line?
A heat patch production line is an integrated manufacturing and packaging system that forms patch-style products and packs them into sealed pouches in a continuous workflow. Depending on the product, the line may include material feeding, dosing/filling (including powder filling where required), pouch forming or pouch handling, sealing, and finished product discharge—designed to run with stable speed and consistent quality.
This automatic heating patch production line integrates feeding, forming, filling, sealing and cutting. It features stable operation, high automation and high output, suitable for the production of warm body patches, warm palace patches and other heating products. The line uses PLC control system, simple operation, easy maintenance, stable quality, effectively reducing labor costs, widely used in daily chemical and health care products manufacturing plants, to meet mass production needs.
Typical workflow we build for warm patch and patch-style products
While the exact steps depend on your product format (hand warmer, knee patch, neck sticker, waistband, steam eye mask, etc.), most projects follow a clear production logic:
Material feeding (single, dual, or additive feeding): We match the feeding method to your material behavior and dosing needs.
Accurate filling / dosing: For products that require powder filling, we configure dedicated filling structures to improve consistency and reduce waste.
Forming and positioning: The line manages product placement and pouch alignment to support stable sealing.
Sealing and output: Consistent sealing is essential for storage stability and appearance; output is designed for efficient collection and secondary packing.
This structured approach is why many customers choose a line-level solution instead of combining unrelated machines—line rhythm and process matching are planned from the start.
Modular configurations for different product types
One key reason customers come to us is that patch products vary widely in structure and filling requirements. To fit different manufacturing goals, we provide a range of modular, purpose-built machines, including:
Single-Feed Warm Patch Machine HY-350 and Dual-Feed Warm Patch Packaging Machine HY-330 for different feeding and throughput needs
HY-330 Warm Patch Packaging Machine and HY-330A Double-Additive Warm Patch Machine for formats requiring additional material handling flexibility
Auto-Fill Knee Patch Packaging Machine / Knee Patch Packaging Machine for patch products with dedicated forming and packing requirements
Auto-Fill Powder Neck Sticker Machine HY-600CSB for powder-fill patch formats
Automatic Single-feed Waistband Production Line for waistband-style products
Automatic Steam Eye Mask Production Line for eye-mask format production requirements
Automatic Hand Warmer Packaging Machine and Double-Feed Foot Warmer Packaging Machine for hand/foot warmer formats
By selecting the correct feeding method and filling structure, we help reduce instability caused by inconsistent dosing, misalignment, or sealing-area contamination—common issues that limit real output in patch packaging.
How we support OEM customization and project delivery
We do not treat a “production line” as a single standard SKU. We support OEM modification and customization based on your target product, pouch format, material characteristics, and desired output. Our goal is to deliver a line that is practical to run daily—easy to maintain, stable in rhythm, and consistent in finished quality.
To reduce selection risk, we can validate key points through pre-delivery checks and trial-based evaluation (where applicable), so the final configuration aligns with your packaging effect expectations.
What we need from you for accurate line selection
To recommend the right solution efficiently, we typically confirm:
product type (hand warmer, knee patch, neck sticker, waistband, steam eye mask, etc.)
filling requirements (single-feed, dual-feed, additive handling, powder filling)
pouch size range and packaging film structure
target output and shift plan
downstream needs (secondary packing, cartoning, shrink wrapping)
From single machines to complete production lines, we provide professional overall solutions for packaging machinery. If you are planning a new heat patch project or upgrading an existing line, we can help you build a heat patch production line that balances throughput, stability, and long-term service support.
