Quick Detail:

1. Reactive PUR Packaging: Specialized packaging for moisture-curing polyurethane hot melt adhesives.

2. Round Bottom Design: Facilitates complete adhesive discharge, minimizing waste.

3. Multi-layer Barrier: PA/AL/PA/Modified film structure ensures excellent moisture & oxygen barrier.

4. High-Temperature Resistance: Withstands up to 165°C, compatible with various lamination processes.

5. Leading Supplier: 11-year focused manufacturer with monthly capacity of 3 million bags.

Description:
Shaoguan Bonding New Materials Co., Ltd., a leading supplier with over a decade of expertise, specializes in manufacturing high-performance Aluminum Foil Round Bottom Bags specifically designed for packaging reactive PUR (Polyurethane Reactive) hot melt adhesives. These adhesives are critical in industries like composite panel manufacturing (e.g., for RVs, refrigerated trucks). Our bags are engineered with a robust 4-layer structure (PA/AL/PA/Modified Film) that provides an exceptional barrier against moisture and oxygen, which is crucial to prevent premature curing of the PUR adhesive and ensure its optimal performance during the lamination process. The unique round bottom design allows for near-total adhesive evacuation, reducing residue and cost. With a high heat resistance of up to 165°C and customizable sizes, our bags are the reliable packaging solution trusted by major adhesive manufacturers and panel producers worldwide.

Specifications

Notices:

1. Storage: Store in a cool, dry place away from direct sunlight and moisture to preserve the adhesive's shelf life and the bag's barrier integrity.

2. Usage: Ensure the bag is compatible with your specific PUR adhesive grade and lamination process temperature.

3. Handling: Although durable, avoid sharp objects or excessive abrasion that could puncture the aluminum layer.

4. Customization: We offer various temperature resistance grades (High: 165°C, Medium: 145°C, Low) and sizes. Confirm your requirements before ordering.

Applications:
Essential consumable for the composite panel industry:

1. Vacuum Bagging Lamination: Used as the vacuum bag in processes like those performed by the LY-07-3000 Laminating Machine to create RV and truck panels.

2. PUR Adhesive Packaging: The primary packaging for reactive polyurethane hot melt adhesives supplied to panel manufacturers.

3. General High-Barrier Packaging: Suitable for packaging other moisture-sensitive or oxygen-sensitive chemicals and materials.

FAQ
Q1: Why use an Aluminum Foil Bag for PUR glue?
A1: PUR adhesives cure upon reaction with moisture in the air. The aluminum foil layer in our bag provides an impermeable barrier to both moisture and oxygen, effectively sealing the adhesive inside and preventing it from curing during storage and transport until it is ready for use.

Q2: What is the benefit of the "Round Bottom" design?
A2: The round bottom allows the adhesive to flow completely to the dispensing point, minimizing leftover residue in the bag corners. This reduces waste, ensures more consistent adhesive application, and improves cost-efficiency for the end-user.

Q3: Can you supply bags for our specific adhesive packaging line?
A3: Yes, customization is our strength. We can produce bags in various sizes (from 0.5L to 200L and beyond) and with different material specifications (e.g., varying AL thickness, film types) to match your filling equipment, adhesive properties, and process requirements.

Q4: Are you only a bag supplier, or do you understand the lamination process?
A4: As a subsidiary of Guangdong Longyu Machinery Equipment Co., Ltd. (which makes laminating machines like the LY-07-3000), we have deep process knowledge. We understand how the bag performs under vacuum and heat, allowing us to provide technically informed support and product recommendations.
