Non-Stick Inner Asphalt Patch Repair Bag | Open Mouth Color Woven Bag | Easy Release Design to Minimize Material Waste

Product Overview: 
This product is a non‑stick, inner‑wall asphalt repair agent bag, specially designed for packaging asphalt‑based repair materials. It features a flat‑mouth, color‑printed woven‑bag construction, with a specially treated inner surface that prevents the asphalt material from adhering after filling and ensures smooth release during pouring, significantly reducing material residue and waste. It is suitable for packaging viscous, high‑viscosity materials such as asphalt repair agents, cold patching compounds, and joint sealants.

Applicable materials: 
Asphalt repair agents, cold‑mix asphalt, pavement joint sealants, asphalt mastics, sealants, epoxy resin repair materials, polymer‑based road repair materials, and other high‑viscosity construction materials.

Product Structure: 
The outer layer is made of PP polypropylene woven fabric, providing excellent tensile strength and puncture resistance. The inner wall is coated with a non‑stick release coating, creating a physical barrier against asphalt materials. The bag features a flat‑bottom design with a smooth, open mouth, compatible with various filling methods. The bottom is reinforced with sewn seams. Printing is done using full‑color laminated printing, ensuring brand information is clear and highly visible.

Core Advantages: 
Non-stick interior design 
The inner wall is coated with a special non-stick layer, ensuring that the asphalt repair agent does not adhere to the bag walls after filling. During pouring, the material releases smoothly without the need for scraping, tapping, or other auxiliary operations.

Easy demolding reduces waste. 
This product features a non-stick inner surface, achieving a material release rate of over 95%, significantly reducing material waste per bag and delivering substantial long-term savings on material costs.

Environmental protection and energy conservation 
Reducing material residue means less packaging waste pollution. At the same time, there’s no need to heat or use solvents to soften residual materials, thereby lowering energy consumption and operational risks.

Flat‑mouth design is suitable for high‑viscosity materials. 
The flat‑bottom bag features a wide opening, making it better suited than valve bags for filling high‑viscosity asphalt materials. It offers low material flow resistance, ensuring smooth filling and minimizing the risk of blockages. After filling, the bag can be sealed by sewing.

Color-printed laminated brand display 
Surface color printing with lamination ensures the brand logo and product information are clear and eye‑catching. The laminated layer is waterproof and abrasion‑resistant, keeping the packaging neat even in construction‑site conditions.

Material and Craftsmanship: 
The outer layer is made of PP polypropylene woven fabric, with a basis weight customized to meet load‑bearing requirements. The inner wall is coated with a non‑stick release coating that ensures uniform thickness and strong adhesion. The bag features a flat‑bottom design, with a reinforced double‑stitched seam at the base. Printing is performed using full‑color offset printing followed by lamination.

Tensile strength: 
Testing has confirmed a tensile strength of at least 650 newtons per 50 millimeters, capable of supporting 10 to 25 kilograms of asphalt repair material.

Packaging drop test: 
Under a 25-kg load condition, following a 1.2-meter free-fall test, the product remained intact and showed no leakage after being dropped from all six sides.

Applicable filling method: 
Compatible with screw fillers, gravity fillers, and manual filling. The flat‑mouth open‑design is particularly well suited for the smooth dispensing of high‑viscosity materials.

Sealing method: 
After filling, the package is sealed with a sewing‑machine stitch, using double‑needle reinforcement to ensure a secure seal that won’t come undone. A sealing strip can be optionally added to further enhance leak‑proof performance.

Packaging specifications: 
The loading weight can be customized to 10 kg, 15 kg, 20 kg, or 25 kg. Bag dimensions are tailored to the specified loading weight and customer requirements. The bag style is a flat‑bottom pouch, with a reinforced sewn bottom.

Customization Scope: 
Dimensions can be customized to suit the weight of the material being loaded. Printing supports full-color printing with lamination, and brand logos and product information are customizable. The non-stick coating formulation can be adjusted according to the viscosity of the material. Thickness can be tailored to meet specific requirements by adjusting the basis weight of the woven fabric.

Environmental Compliance: 
The product is manufactured using virgin PP material, and its woven layer is recyclable. The non-stick coating meets the packaging requirements for road repair materials.

Applicable to: 
This product is suitable for asphalt repair agent manufacturers, cold‑mix asphalt material producers, pavement joint‑sealing adhesive companies, road maintenance material suppliers, sealant manufacturers, and building‑material exporters.

Price and MOQ: 
Specific pricing and MOQ are negotiable.
