When should you use polythene mailing bags verses flat postal boxes? It all comes down to what you are sending and how much protection you want. Here we take a look at the advantages of each – and find that they can also work really well together.
When is it best to use polythene mailing bags verses flat postal boxes? As more people are looking to send more goods through the post and via courier – all over the world – what to pack things in is becoming ever more important.
The first question you need to ask is what is being sent and where is it being sent. Items that are relatively flat and likely to go through a letter box are perfectly suited to flat postal boxes. Things such as computer keyboards, or framed pictures or even things such as homewares and arts and crafts.
For these things cardboard postal boxes offer excellent protection from impact, dust, dirt and some moisture. They can also be padded out inside with other packaging materials such as bubble wrap.
Polythene mailing bags, on the other hand, are very good for soft, lightweight, non-fragile items, particularly clothing and apparel. They are also waterproof.
While postal boxes, then, are ideal for more delicate items that need impact protection, waterproof bags are ideal for moisture protection. Perhaps this isn’t and either/or decision: perhaps the ideal mailing solution for your more fragile items is to use both?
Say you are sending a computer keyboard, or a clock to a customer in France. You want to be able to pack that in a box with bubble wrap so that it is protected from vibration, impacts and isn’t free to move about. But you also want it to be protected from moisture.
Putting it in the postal box and then putting that in to a polythene mailing bag can make for the ideal packaging solution: impact protection and waterproof. The poly bag may even give it a handy handle to help the deliverer carry in more safely.
Polythene mailing bags offer a number of benefits. Standard polythene mailing bags, as we have seen, are waterproof, so they can protect against moisture. They are also made from tough polythene and have tamper-proof peel and seal openings, so that they also offer a good degree of security – something enhanced by those bags that are grey or black opaque polythene which precludes anyone seeing what is inside the package.
Being flexible, they are also ideal for soft items such as homewares and apparel and are increasingly becoming a staple of the online fashion business as their toughness also makes them suitable for being re-used for returns. Their toughness also makes them ideal for other uses. Clear polythene bags and clear bags with write on labels are often used for sending out brochures and catalogues, displaying the goods inside and allowing for the label to be clearly visible to the courier.
Mail bag polythene envelopes with handles are also quite useful for delivery of clothing and other soft items, protecting what’s inside and making them easy to carry.
For protecting more fragile items, such as jewellery and some homeware items, polythene bubble mail bags can be used. These offer the same advantages as other mailing bags, but are lined with bubble wrap which adds a whole extra layer of impact protection and makes them a viable alternative in this regard to flat pack postal boxes for some items.
Flat boxes offer a range of benefits too. Flat mailing boxes are ideal for protecting fragile objects, since the think card from which they are constructed offers excellent impact protection.
Flat pack postal boxes also come in a wide variety of sizes and shapes – and some feature some novel ways to offer flexibility around what you want to send as well as enhanced protection.
For example, double wall, flat telescopic boxes come in a wide range of sizes and form factors and are ideal for sending pictures, mirrors and other flat glassware that needs total protection and flexibility around size.
These telescopic boxes can accommodate a variety of sizes, since the lid of the box can slide up and down the main part of the box. Large foldable flaps, meanwhile can create a box that offers an extra layer of protection to delicate items, with the flaps folding over to create an extra barrier. Both these and telescopic boxes also have the advantage of offering a pleasant ‘unboxing’ experience for the recipient – something that is increasingly important in the competitive ecommerce field.
One piece, five panel wrap boxes not only come in a range of sizes, but also offer a one piece wrap-around experience. They also have reinforced corners, making them even tougher and impact resistant.
Flat cardboard boxes also come in a range of sizes and shapes to suit almost all types of goods and to allow some leeway for adding extra packaging materials around the goods and within the box to give what’s inside even more protection.
Polythene mailing bags and flat postal boxes have some common traits too. We have already seen that the choice between flat cardboard postal boxes and polythene mailing bags is not necessarily an either/or choice: working together, they can provide total protection for goods in transit, tapping into the benefits of both.
They also have a lot in common. They are both lightweight and can be used for many of the same things: some apparel, for example, can be just as easily sent in a box as a bag, and it can lend an air of luxury to the product.
Likewise, using bubble wrap or bubble-lined bags, some delicate items such as watches and other electronics can be sent in plastic.
Both are also recyclable, with both the cardboard and the polythene being recyclable once used at any recycling point.
In addition, both are also available made from recycled cardboard and polyethene – a win-win.
Mailing envelopes are a type of packaging material that is commonly used to send documents, letters, and small items through the mail. They have become an essential component of modern communication and commerce.
Whether you need to send a birthday card or a business letter, they offer a convenient and reliable way to get your message or package where it needs to go. These envelopes can come in different sizes, colours, and materials such as paper, cardboard, or plastic.
Here are a few things you should know about mailing envelopes:
The UK follows the standards set by the ISO when it comes to envelope size. The Royal Mail deviates from this standard, but using an envelope no larger than C5 is a safe bet.
When it comes to sending mail, choosing the right envelope is crucial. There are several types of mailing envelopes that you can choose from depending on your specific needs. Let’s take a closer look at each of them:
Standard envelopes are the most commonly used envelopes for mailing letters, invoices, and other important documents. They are usually made from paper and come in different sizes, with the most common being the DL envelope. These envelopes typically have a rectangular shape and a gummed flap that can be sealed.
Window envelopes are similar to standard envelopes but have a transparent window on the front that allows the recipient’s address to show through. These envelopes are convenient for businesses that send a large volume of mail and can save time because you don’t have to manually write or print the address.
Padded envelopes are a great option for sending fragile items such as jewelry, CDs, or DVDs. They are made of padded material on the inside to protect the contents and usually have a self-sealing flap.
Bubble mailers are another type of envelope for sending fragile or delicate items. They have a layer of bubble wrap inside that cushions the contents and protects them from damage. Bubble mailers come in different sizes and styles and can have anywhere from one to three layers of bubble wrap.
Choosing the right type of mailing envelope can help ensure that your mail is delivered safely and securely. Consider your contents, recipient, and postage requirements before selecting the best envelope for your needs.

Mailing envelopes are a great choice for many purposes. Here are some scenarios where you should consider using them:
Mailing envelopes are perfect for sending letters, documents, or other similar items. They come in various sizes, so you can choose the one that fits your needs. For instance, if you need to send a legal document, you can use a legal-sized mailing envelope to ensure that it fits perfectly and stays neat.
Mailing envelopes are also great for lightweight items such as photographs, books, and small items like jewelry or small clothing accessories. They offer a cost-effective way to send these items, as you can often send them through regular mail without having to spend extra on shipping.
If you’re sending flat items, such as artwork, certificates, or posters, mailing envelopes are the perfect choice. They are designed to be flat, which makes them ideal for these types of items. Plus, they offer protection during transit, ensuring that your item doesn’t get damaged.

Mailing bags are large, flexible bags made of lightweight materials such as polyethylene or polypropylene. They are used for packaging and shipping various goods, documents, and envelopes that do not require extra padding or protection. Generally, mailing bags have a self-sealing strip that makes them easy to use and secure.
Mailing bags offer several useful benefits that make them popular for shipping various items. Here are some of the advantages of using mailing bags:
When it comes to mailing goods, envelopes aren’t always the best option. Sometimes you need something sturdier, more spacious and versatile. That’s where mailing bags come in. There are several types available, each with their own unique features and benefits. Let’s take a look at some of the most common ones:

Bubble wrap mailing bags are a great choice if you need extra protection for your items during transit. They feature a layer of bubble wrap lining on the inside, providing cushioning and shock absorption. They come in a range of sizes and are perfect for fragile items like glass, electronics and ceramics.
Consider paper bubble wrap mailing bags if you want the same protection, but without the carbon footprint.
Tamper-evident mailing bags have become increasingly popular in recent years due to security concerns. They feature a special seal that shows if the bag has been opened or tampered with. They are great for sending valuable items and confidential documents.
Gusseted mailing bags are perfect for sending bulkier items, such as clothing or soft toys. They feature expandable sides or a “gusset”, which give the bag extra depth and room for the items to move around. They are available in a range of sizes and colors.
While mailing bags have their benefits, it’s important to note that they’re not suitable for all items. If you’re shipping something valuable, fragile or that requires extra protection, always opt for a box or a padded envelope.
Here are some scenarios when using mailing bags might be the best choice:
Mailing bags are not suitable for fragile items or those that require special handling. However, they are ideal for shipping items like books, documents, and small electronics that can withstand some movement or handling during transit. They’re perfect for shipping clothes, especially lightweight fabrics that don’t require extra padding.
Mailing bags are great for flat items that can be easily inserted into the bag and don’t require additional assembly or preparation. This makes them a perfect choice for shipping items like stickers, prints, and posters.
Mailing bags are typically lighter than boxes, which means they can save you money on shipping costs. They’re also easier to store and pack, which makes them a great option for small businesses or online sellers.
