Frequently Asked Questions

What is a 12 x 16 x 1 expansion envelope used for?

A 12 x 16 x 1 expansion envelope is engineered for securely mailing or storing bulky documents, binders, annual reports, large catalogs, and thick booklets. The crucial 1-inch gusset provides extra capacity, preventing bending or tearing, making it the ideal solution for businesses shipping thicker materials.

What does 37# Golden Kraft paper mean?

The designation “37# Golden Kraft” indicates a premium paper stock weight and color finish. The 37-pound heavy paper stock provides superior durability and thickness compared to standard materials, while the Golden Kraft finish gives it a professional, premium golden-brown appearance, resisting tears and punctures during transit.

How does the Peel & Seal closure work?

Peel & Seal envelopes feature a strong, pressure-sensitive adhesive strip protected by a removable liner. Users simply remove the liner and press the flap firmly to seal. This method provides an instant, secure bond that eliminates the need for moisture and creates a tamper-resistant closure.

Are expansion envelopes cost effective for bulk mailing?

Yes, expansion envelopes are highly cost effective for shipping multi-page or thick items because they reduce the need for expensive boxes while offering comparable, lightweight protection. Purchasing in bulk, such as a box of 125, significantly lowers the per-unit cost for businesses with high-volume mailing needs.

What is the difference between Golden Kraft and Brown Kraft envelopes?

Golden Kraft envelopes feature a premium, slightly smoother finish and a lighter, distinct golden-brown hue. Brown Kraft offers a darker, more traditional natural appearance. While both materials are strong and tear resistant, Golden Kraft is often preferred for its elevated, professional aesthetic in business mailings.

Can 12 x 16 x 1 envelopes be mailed through USPS or courier services?

Yes. These large 12 x 16 x 1 envelopes meet USPS standards for large envelopes (flats), provided the total thickness remains within regulations. They are widely accepted by all major courier services for both domestic and international shipments, making them versatile for logistics.

How do I measure an expansion envelope correctly?

An expansion envelope is measured by its three dimensions: the width (12 inches), the height (16 inches), and the gusset depth (1 inch). The gusset measurement specifies the expandable capacity built into the side or bottom to accommodate bulkier contents.

What makes these 37# Golden Kraft envelopes tear resistant?

These envelopes are made from heavy-duty, 37# high-density Kraft paper engineered with a strong, highly durable fiber structure. This premium composition, combined with the secure Peel & Seal closure, delivers superior tear resistance against external pressure, ripping, and environmental wear during shipping.

What our customers say

Siobhan Jones

WONDERFUL! We ordered 10,000 envelopes that were printed with 2 designs. the team were fantastic and patient as we had a small design issue, which they helped us through! I would 100% recommend All Colour Envelopes, as the service was professional, the turn around only 5 days and the communication impressive!

Thankyou!

Kelly Donaldson

I searched long and hard for a company that sold the envelopes I needed (which were an unusual size) and 'All Colour Envelopes' were the only company that did them. Their website is very easy to use and the envelopes arrived within a few days. Great service!

Stephen Devaney

Quality of the product is fantastic. Delivery was on time and even early on one. The packaging is brilliant to make sure that the product arrives in perfect condition.

Judith White

I've ordered from All Colour Envelopes a couple of times and the service has been great - nothing was too much trouble.

Jess looked after me both times, sending sample envelopes to make sure that I was sent exactly what I wanted. The orders were put through quickly and delivered on the next working day.

I recommend this company and will use them again.

Been using ACE since opening my business. The envelopes are the best I can find, and customer service has always been amazing when I’ve had issues with something. Can’t imagine using anyone else. Don’t get me wrong, I’ve looked on occasions but I always end up ordering from ACE
