75gsm Kraft Paper + 10g Poly Laminated Inside Raw Material Rolls For Moisture Proof Envelopes

Envelope Kraft Paper // Introduction

Durable Protection Meets Essential Moisture Barrier
This innovative material combines the natural strength of 75gsm kraft paper with an interior PE laminate (8gsm or 10gsm) to create a reliable base for manufacturing protective envelopes. The kraft exterior provides a classic, professional look and inherent tear resistance, while the internal polyethylene coating forms an effective barrier against moisture, humidity, and light environmental liquids. It is specifically engineered as a raw material for producing envelopes that require extra protection for their contents without the bulk or cost of fully synthetic materials.

Envelope Kraft Paper // Advantages

♦ Built-In Moisture Resistance
The continuous PE layer effectively blocks moisture, humidity, and light spills, preventing damage to envelope contents during transit or storage.

♦ Enhanced Durability
Kraft paper's natural tear resistance is preserved while the PE coating adds extra strength, reducing the risk of splitting at seams or corners.

♦ Professional Appearance
The uncoated kraft exterior maintains a natural, eco-friendly look that is easily printable and ideal for branding, while the hidden interior coating provides protection.

♦ Heat Sealable Seams
The interior PE layer allows for clean, strong heat sealing during envelope manufacturing, creating secure and leak-proof seams.

♦ Lightweight Protection
Offers a superior barrier compared to standard paper without significantly increasing weight or thickness, keeping shipping costs manageable.
