What is kraft paper with polyethylene?
Kraft paper with polyethylene is a material made up of a sheet of kraft paper — known for its high mechanical strength — coated with a layer of polyethylene. This coating provides waterproofing and acts as a barrier against moisture, grease and oils.
The combination of both materials offers the perfect balance between the natural rigidity of paper and the technical properties of polyethylene. Within this category, creped kraft paper with polyethylene stands out for its enhanced elasticity and adaptability, ideal for wrapping irregularly shaped objects or items that require extra protection against impact and deformation.
Applications of kraft paper with polyethylene
Kraft paper with polyethylene is an extremely versatile material, widely used across various industrial sectors:
Industrial packaging
Used to protect metal parts, spare components, automotive elements and machinery during transport or storage. Its tensile strength and cushioning ability make it ideal for demanding applications.
Food industry
Kraft paper with polyethylene is commonly used as a separator or wrapper for greasy food items such as cured meats, pastries or cheeses, thanks to its moisture- and grease-resistant barrier.
Logistics and e-commerce
Used as inner reinforcement in envelopes or boxes, it protects products from condensation or leaks during shipping.
Pharmaceuticals and cosmetics
Serves as an outer coating for moisture-sensitive products or as part of secondary packaging, where additional protection and visual appeal are essential.
Protection of irregular shapes
Creped kraft paper with polyethylene is especially suited for wrapping objects with complex geometries. Its stretchable texture allows easy adaptation without compromising barrier properties.
Advantages of kraft paper with polyethylene
One of the main strengths of kraft paper with polyethylene is its outstanding mechanical resistance. It withstands handling, stress and temperature fluctuations without tearing or losing its protective properties.
Other notable advantages include:
- Waterproofing: the polyethylene layer blocks the passage of liquids and fats.
- Ease of use: it can be cut, die-cut or heat-sealed in automated processes.
- Natural appearance: the kraft finish offers an eco-friendly image valued by consumers.
- Adaptability: the creped version offers greater flexibility without sacrificing strength.
Comparison with other packaging materials
Compared to 100% plastic materials
Kraft paper with polyethylene reduces the proportion of non-recyclable components while maintaining excellent protective properties. It represents a middle ground between functionality and sustainability.
Compared to waxed paper
Offers better tensile strength, improved moisture resistance and greater dimensional stability.
Compared to complex plastic films
Kraft paper with polyethylene is easier to handle and more cost-effective in industrial processes. Its creped version also offers cushioning properties that many films lack.

Sustainability of kraft paper with polyethylene
There are now versions of kraft paper with polyethylene that include recycled content or allow layer separation to facilitate recycling. Additionally, some manufacturers are developing biodegradable coatings that maintain similar barrier properties.
Kraft paper is a renewable material, and its combination with a thin polyethylene film remains a more sustainable option than using plastic alone in packaging. This complies with new European regulatory requirements and growing market demand for responsible solutions.
Conclusion
Kraft paper with polyethylene is an effective, strong and versatile packaging solution that meets both the technical and environmental needs of today’s businesses. Whether in its standard or creped version, this material stands out for its protective qualities, ease of use and positive brand image.
