Greeting Card Dimensions: A Simple Guide to Standard Card Sizes
6 September 2026
Picking the right greeting card size is one of those things that seems simple until you actually start designing one.
The Printed Packaging offers quality 7mm mylar bags made for UK brands that need their products to be treated to serious barrier protection. The Printed Packaging’s heavy-duty, odour-proof pouches keep your herbs, coffee, spices, snacks, and bulk goods fresher for longer. Available in 1g sample bags or 1lb bulk pouches, in full-colour, matte, gloss, and metallic finishes and with optional child-proof zippers and clear display windows. We also have eye-catching Custom Display Boxes for your products on the shelf. Low-MOQ short runs starting from 100 units or bulk orders as low as £0.15 per unit, The Printed Packaging can provide you with high quality, ready packaging for your brand.
In terms of preserving freshness, blocking odours, and protecting your product from light and moisture, 7mm mylar bags are one of the most trusted packaging solutions available on the market today. Here at The Printed Packaging, we provide the perfect, smell-proof mylar pouches for UK brands that need reliable barrier protection and personalised branding. Whether you are packaging herbal blends, coffee, snacks, or bulk dry goods, our 7mm mylar bags can provide the strength, shelf appeal, and durability that you need.
The 7mm thickness refers to the thickness of the film used, giving these bags a stronger, more puncture-resistant feel compared to standard thin-film pouches. These bags are ideal for products that have to endure shipping, handling, and storage without tear or losing their seal. With foil lined, 7mm mylar bags help shield against UV light, oxygen, and moisture — the biggest threats to product freshness.
The Printed Packaging can personalise any 7mm mylar bag with your brand’s logo, colour and finish, making a simple pouch an optimum retail product.
What size mylar bag do I need? “Sizing depends entirely on the weight and volume of the product you’re packaging. We have a small 1 gram sample bag (3″ 4″) to a large 1-pound bulk storage bag (13″ 15″). For example, a 3.5-gram product will fit best in a 3.5” 5” pouch, whereas a 1-ounce (28g) product will fit better into a 6” 9” bag with some extra headroom for sealing and labeling.
If your product isn’t a standard size, The Printed Packaging also offers custom sizes made to your product requirements, without compromise on fit or presentation.
Pricing for 7mm mylar bags is dependent on order quantity, method of printing, and finishing options. Short-run orders of 100-500 units are typically between £0.35–£0.60 per unit for plain bags or £0.80–£1.20 per unit for full custom printing. As order numbers increase, the cost per unit drops dramatically – orders of 25,000+ units could see prices as low as £0.08 per unit for plain bags or £0.15 per unit for fully printed bags.
Many factors impact where your final price falls within these ranges.
Printing Technique – Digital printing works well for smaller runs and quick turnarounds, while gravure plate printing becomes more cost-effective at higher volumes with sharper colour reproduction.
Surface Finishes – Matte, gloss, soft-touch, holographic, and metallic foil finishes each carry different production costs and visual impact.
Add-On Closures – Features like child-resistant (CR) zippers, tear notches, clear display windows, and Euro slot hang holes add functionality but also affect unit pricing.
Standard turnaround times for small orders are 5 to 7 working days, and 10 to 12 working days for large quantities. Special times can be negotiated on very large orders.
Is your product a few samples in a box or perhaps you need tens of thousands of bags?
