Non woven fabric can be used to make cement packaging bags, especially with the development trend of environmentally friendly packaging and recyclable materials. More and more companies are using non-woven fabric materials to replace traditional woven bags. The following is a point by point introduction:
1、 Feasibility of using non-woven fabric for cement packaging bags
●Adjustable structural strength
The load-bearing capacity and tear resistance can be enhanced by thickening, hot pressing composite, laminating, and other methods.
●Moisture resistant and leak proof treatment
The surface can be covered with PE film or coated to enhance moisture and water resistance, and meet the requirements of cement storage.
●Superior environmental performance
Most non-woven fabrics are recyclable or biodegradable, reducing environmental pollution and meeting the packaging standards for green building materials.
2、 The advantages of non-woven cement bags
●Lightweight and easy to transport
Compared to traditional three-layer kraft paper bags or woven bags, it has a lighter weight and reduces logistics costs.
●Customizable printing, beautiful appearance
Easy to color print and customize logos, enhancing brand image.
●Good durability and aesthetically pleasing packaging
Through composite structure design, good stiffness and compressive performance can be achieved.
●Support the use of automatic packaging machines
Valve ports and open bag types can be designed according to requirements to adapt to automated filling production lines.
3、 Common structural combinations
●Non woven fabric+PE coated composite bag
Waterproof and dustproof, suitable for outdoor storage.
●Non woven fabric+woven fabric+inner membrane bag
Enhance strength and sealing, suitable for heavy packaging needs.
●Coated non-woven bag (laminated type)
More barrier properties, extending the shelf life of cement.
4、 Scope of application
●Cement, dry powder mortar, putty powder
●Building adhesive, expansion agent and other dry powder materials for construction
●Agricultural fertilizers and feed (similar bag type)
5、 Precautions
●The load-bearing limit needs to match the weight of the product
It is recommended that each bag should not exceed 25kg or 50kg, and the load-bearing capacity should be determined according to the structure.
●Moisture proof treatment must be reliable
Cement is prone to moisture absorption and clumping, and high-quality laminated non-woven fabric or composite materials should be used.
●The storage and handling methods should be adapted to the performance of the bag material
Try to avoid strong pulling or throwing from a high place to prevent tearing.
