PE-coated kraft paper, 70 gsm - 20 zem

PE-Coated Kraft Paper 70gsm - 20zem: A Comprehensive Waterproof and Anti-Mold Solution

In long-term warehousing and export packaging operations, moisture, water vapor, and grease are silent "enemies" that actively degrade product quality. To solve this problem fundamentally, PE-coated Kraft paper (70gsm basis weight, 20zem coating layer) was researched and developed as a next-generation multipurpose packaging material. It perfectly combines the durability of traditional Kraft paper with the absolute moisture-proof and antibacterial protection of a PE plastic film.

Join Viet Hung An to explore the technical structure, outstanding benefits, and practical applications of this specialized product line in the article below.

1. Decoding Technical Specifications: What Do 70gsm & 20zem Mean?

Understanding technical parameters is extremely important when ing the right material for your packaging lines:

• 70gsm Kraft Base Paper: Refers to the natural Kraft paper base which weighs 70 grams per square meter. This is the gold standard weight for wrapping paper lines due to its ideal thickness and high flexibility. It can easily bend and fold without tearing when wrapped around sharp product corners.

• 20zem PE Coating: "Zem" is a common thickness measurement unit in the Vietnamese plastic and packaging industry, where 1zem equals 0.1mm (or approximately 10 microns in some thin-film measurement conventions, meaning a 20zem coating equates to a 20-micron layer). The 20zem PE film is heat-laminated directly onto the Kraft paper surface, forming a micro-thin yet perfectly uniform, peel-resistant layer that acts as an absolute barrier against liquids.

2. Outstanding Advantages of PE-Coated Kraft Paper 70gsm - 20zem

This smart material combination delivers exceptional physical and chemical properties to the product:

• Absolute Waterproofing and Grease Resistance: The 20zem PE layer prevents external water and environmental moisture from penetrating the goods, while simultaneously keeping anti-rust oils (on mechanical components) from leaking out and staining carton boxes.

• Enhanced Tensile and Tear Strength: The PE plastic film binds tightly with the cellulose fibers of the Kraft paper, boosting mechanical load-bearing capacity. This makes packages sturdier and prevents them from rotting or tearing when exposed to humid environments in ocean containers.

• Heat-Sealing Compatibility: Thanks to the plastic PE layer, this paper can be effortlessly sealed using heat-sealing machinery to create airtight protective pouches without requiring adhesive tapes or metal staples.

3. Practical Applications in Key Export Industries

Thanks to its "2-in-1" protective properties, PE-coated Kraft paper 70gsm - 20zem is widely applied across multiple fields:

3.1. Packaging Mechanical Components, Metals & Machine Parts

Metal parts are usually coated with a layer of rust-preventative oil after processing. PE-coated Kraft paper is the number one choice for wrapping these components. The PE layer keeps the maintenance oil from drying out or seeping through, while blocking humidity from entering to prevent oxidation and metal surface rust.

3.2. Export Agricultural & Food Industry

With a lamination thickness of 20zem, this product meets strict Food-contact safety standards. The paper is widely used as carton box bottom liners, packaging bags for dry nuts (coffee, pepper, cashews), or lining sheets for export fruits. This helps regulate humidity and prevents condensation that causes rot or fruit bruising inside containers.

3.3. Premium Garment & Footwear Export Packaging

For clothing and leather shoe orders exported to high-humidity regions or shipped via long ocean voyages, using PE-coated Kraft paper to wrap batches of goods or line inside jumbo cases eliminates mold risks completely, preserving the fresh scent of fabrics and leather materials.

4. Strict International Standards Met by Viet Hung An

When exporting goods to the US, EU, or Japan, accompanying packaging materials must also pass strict technical barriers. PE-coated Kraft paper from Viet Hung An proudly meets:

• RoHS Standard: Completely eliminates 10 hazardous substances (lead, mercury, cadmium...), ensuring absolute safety for handlers.

• FFS / Food-contact Certification: Fully complies with food hygiene and safety standards for agricultural packaging applications.

• Quality Control per Test A01 Standards: Guarantees that chemical content throughout the supply chain is monitored under the strictest regulations.
