A4 COPY PAPER

75 GSM vs 80 GSM: what actually changes?

Weight

For the same A4 sheet area, 80 GSM paper carries more mass than 75 GSM. This affects ream and carton weight and therefore logistics planning.

Handling

Grammage is not the only determinant of paper feel. Caliper, stiffness, moisture and fiber characteristics also influence feeding and handling.

Printer performance

Before changing GSM, test the paper in the target printer or copier fleet. Curl, dust, moisture and dimensional stability can matter as much as grammage.

SUPPLIER EVALUATION

A professional RFQ should define the product before asking for price.

01

Technical specification

Define size, GSM, tolerances, raw material, packaging, performance requirements and acceptable alternatives.

02

Commercial specification

State quantity, shipment frequency, destination, Incoterm, payment expectations and required documentation.

03

Evidence

Use samples, TDS/COA where applicable, packaging photographs, factory information and shipment history to reduce uncertainty.

LANDED COST

Factory price is not the same as delivered cost.

01

Product

Quoted unit price, packaging and any OEM/private-label costs.

02

Origin logistics

Inland movement, export handling, documentation and origin charges.

03

International transport

Freight, insurance where applicable, routing and transit considerations.

04

Destination

Port handling, customs, taxes, inland delivery and other destination costs.

LAMINATION & ADHESIVES

Specification checklist before requesting a quotation.

Lamination film

Film family (BOPP/PET/MPET), thickness, width, roll format, surface treatment, intended substrate, application and required quantity.

Water-based adhesive

Substrates, coating method, solids, viscosity range, drying conditions, line speed, required bond performance, packaging and technical documentation.

FAQ

Common procurement questions

75 GSM or 80 GSM?

Choose based on the required balance of weight, stiffness, opacity, printer performance, market expectation and logistics—not GSM alone.

How should suppliers be compared?

Compare equivalent specifications and the complete commercial package. A lower factory quote is not directly comparable if specifications or delivery terms differ.

Why request samples?

Samples allow practical testing before a commercial shipment and can reveal feeding, curl, dust, bonding or finishing issues that a quotation cannot show.

What makes a long-term supply program?

Consistent specifications, repeatable quality, clear documentation, realistic lead times, responsive communication and commercially workable logistics.
