Polythene Mailing Bag Size FAQs

Q: Can you make mailing bags in custom sizes?
A: Absolutely - any size can be produced. Whether your product is small, medium, or oversized, we’ll create a bag that fits perfectly.

Q: Is a custom size more expensive than a standard size?
A: Not necessarily - all our polythene mailing bags are made-to-order, so custom sizes are priced competitively alongside standard sizes.

Q: Can I order a mix of sizes in one batch?
A: Yes - we can produce multiple sizes in the same order, giving you flexibility for different products without compromising efficiency or pricing.

Q: Are these bags strong enough for heavier items?
A: Yes - bags are lightweight yet durable, designed to protect products in transit. For very heavy or bulky items, we can recommend a suitable thickness and size to ensure safe delivery.

At PiNC, we recommend minimum order quantities (MOQs) that balance efficiency, sustainability, and cost-effectiveness.

• Standard MOQ: 10,000 units

• Extra-large sizes: MOQ can drop to 5,000 units

• Very small sizes: MOQ may increase slightly due to production constraints

These quantities ensure efficient production, optimal pricing, and reduced waste. Smaller or larger runs are possible, but we always provide transparent pricing so you can make the best decision for your brand.

Whether you’re ordering standard or custom sizes, the MOQ is designed to give you the most value while keeping production sustainable and efficient.

At PiNC, we make it easy to turn every mailing bag into a branding opportunity. Your logo, message, or full-colour design can be printed to ensure every parcel reflects your brand.

Spot Colour Printing
We typically recommend 1–4 spot Pantone colours for crisp, vibrant logos that stand out on any bag. Spot colours are cost-effective and ideal for maintaining consistent brand identity across all parcels.

Full-Colour CMYK Printing
For more detailed or photographic designs, CMYK full-colour printing is available. Depending on the artwork and bag size, minimum order quantities may vary, but the result is a stunning, professional finish.

Sustainably Branded
Even with full-colour or spot printing, the bags remain 30% recycled and 100% recyclable, so your branding doesn’t compromise your environmental commitments. We can include this eco messaging as part of the design at no additional cost.

With PiNC, every bag becomes a moving billboard, protecting your products in transit while communicating your brand story with style and impact.

Polythene often gets a bad reputation - but the truth is, when it’s recycled and responsibly manufactured, it remains one of the most sustainable, efficient and reliable packaging options for modern brands.

At PiNC, our recycled mailing bags contain 30% post-consumer material and are 100% recyclable after use. This means they don’t just protect your products - they help close the loop on plastic waste.

Lightweight, durable and space-saving, recycled polythene mailing bags outperform bulkier alternatives. Less raw material goes into making them, fewer vehicles are needed to transport them, and their strength keeps goods safe without the extra weight or cost of boxes.

In short: they save you money, reduce your carbon footprint, and keep your brand aligned with sustainability. That’s why polythene remains the go-to choice for so many leading retailers.

Sustainability FAQs

Q: Isn’t plastic the problem?
A: Virgin, single-use plastic is - but recycled and recyclable polythene is part of the solution. By choosing mailing bags made with 30% recycled content, you’re supporting a packaging system that reuses materials instead of wasting them.

Q: How do polythene mailing bags compare with paper?
A: Paper bags may feel eco-friendly, but they’re often heavier, less durable and more resource-intensive to produce. Recycled polythene offers a lower carbon footprint in manufacturing and transport, while still providing excellent protection.

Q: Can they be recycled easily?
A: Yes. After use, our bags can be recycled through standard soft plastic collection points, ready to be made into new products again.

Q: What makes polythene bags the number one choice?
A: They tick every box: lightweight, protective, low carbon, recyclable and cost-effective. No other packaging combines all of these benefits as efficiently - which is why polythene mailing bags are still the preferred option for sustainable shipping.

Our mailing bags are made from co-extruded (co-ex) film, designed with a black inner layer for complete privacy and a white outer layer for a clean, professional look. This dual-layer structure makes it impossible to see through the bag, keeping your deliveries secure and discreet.

The standard thickness is 60 micron, ideal for everyday e-commerce use, though we can go thicker if your products need extra protection. Co-ex film is about confidentiality and presentation - the go-to choice for brands who want both security and style.

Co-Ex Film FAQs

Q: What is co-ex film?
A: Co-ex (co-extruded) film is made by layering polythene into two or more sheets, usually with a dark inner layer for privacy and a lighter outer layer for branding. It ensures contents can’t be seen through the bag.

Q: Why is the inside black and the outside white?
A: The black inner layer guarantees privacy and prevents contents from showing through, while the white outer layer gives a crisp, professional finish that’s perfect for printing.

Q: How thick are the bags?
A: Our standard co-ex film are 60 microns, which works well for most mailing needs. If you’re sending heavier or bulkier items, we can increase the thickness for extra durability.

Q: Can I choose different colour combinations?
A: Yes. While black inside/white outside is the most popular option, other colour combinations are possible to suit your brand identity.

When it comes to packaging, deadlines matter just as much as design. That’s why we’re upfront about timings from the start. For custom polythene mailing bags, the typical turnaround is 5–6 weeks from artwork sign-off. This allows us to keep production efficient, costs competitive and quality standards exactly where they should be.
