Wholesale kraft paper

When purchasing Kraft paper, the most critical factor is Grammage (GSM), which typically ranges from 60gsm to 450gsm. For heavy-duty packaging, prioritize High-Bursting Strength (measured in kPa) and Tear Resistance. Additionally, verify the Moisture Content (ideally 6-9%) to prevent warping or brittleness during storage and printing.

Virgin Kraft Paper is made from 100% wood pulp, offering superior strength, better printing clarity, and food-grade safety, making it ideal for high-end branding and heavy loads. Recycled Kraft Paper is more cost-effective and eco-friendly, but it has shorter fibers, resulting in lower tensile strength and a slightly rougher texture, suitable for void filling or light-duty wrapping.

If the paper will come into contact with food, it must comply with FDA (U.S.) or EC 1935/2004 (EU) regulations. Ensure the supplier provides FSC (Forest Stewardship Council) certification to prove sustainable sourcing and SGS/TUV lab reports confirming the absence of heavy metals and harmful bleaching agents like chlorine.

Kraft paper is highly versatile and supports Flexographic printing (best for high-volume, low-cost logos), Screen printing (for vibrant, thick ink layers), and Offset printing (for detailed designs). Ensure the paper has a smooth surface sizing if you require high-resolution multi-color printing to prevent excessive ink absorption.

Kraft paper is highly hygroscopic. You must mandate that the supplier uses heavy-duty PE stretch film wrapping and palletized packaging with edge protectors. Request the inclusion of desiccant silica gel packs inside the container and ensure the bill of lading specifies 'Keep Dry' handling instructions.

Focus on Volume-Based Pricing Tiers. Since paper is a commodity, margins are thin; however, you can negotiate better rates by committing to an Annual Purchase Agreement rather than one-off orders. Also, negotiate the Core Diameter and Roll Width to match your machinery, which reduces local processing waste and saves costs.

The most common issue is Grammage Deviation. Always allow for a ±5% tolerance, but reject batches exceeding this. Use a Precision Electronic Balance and Circular Sampler during inspection. Also, check for 'Odour' in recycled paper, as low-quality recycled pulp can retain chemical smells that affect consumer perception.

Be aware of Anti-Dumping Duties (ADD) that some countries impose on paper products from specific regions. Always check the HS Code (typically 4804 for Kraft paper) against your country's tariff schedule.
