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. Lets 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 recipients address to show through. These envelopes are convenient for businesses that send a large volume of mail and can save time because you dont 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 youre 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 doesnt get damaged.

These plastic bags come in many sizes and dimensions. They provide excellent resistance to dust, tampering, and moisture, ensuring that clients receive the items in perfect condition.
There are numerous methods for shipping products to customers, and cardboard boxes will continue to be the best packing for some products. However, there are some situations when poly mailers are a far better and less expensive option.

Their lightweight nature reduces shipping expenses, and they take up less space, further decreasing costs due to dimensional weight considerations.
Flexibility is a major feature; polymailers adjust to the shape of their contents, eliminating unnecessary space. Their composition also contributes to weight savings, leading to lower shipping charges. Other notable characteristics include being water-resistant and protecting against moisture and spills.

Each type of polymailer serves different purposes and offers varying levels of protection, convenience, and branding opportunities to cater to a wide range of shipping needs.
Standard Polymailers: Typically made from polyethene, they are lightweight, water-resistant, and tear-resistant. They are a basic protective envelope for various items and usually come with a self-sealing adhesive strip.
Bubble Polymailers: Equipped with an added layer of bubble cushioning inside, they offer increased protection against shocks, impacts, and vibrations. They are particularly useful for shipping fragile items or those needing more padding during transit.
Returnable Polymailers: Designed with e-commerce in mind, these come with dual adhesive strips. Once the recipient opens the package using the first strip, the second strip can reseal the packaging, making returns hassle-free and efficient. This feature is especially beneficial for businesses that experience high return rates.
Customised Polymailers: These are tailored to businesses needs or branding requirements. They can feature unique colours, logos, designs, and sizes. Beyond aesthetic customisation, they might also have specialised functional features, such as UV protection, antistatic properties, or thermal insulation, depending on the specific requirements of the shipper.

They are ideal for eco-friendly businesses focused on reducing waste and increasing the use of renewable energy because they are safe for both customers and the environment.
Any items in durable packaging: If a product is already in sturdy packaging, packing it in a cardboard box will be unnecessary. On the other hand, poly mailers are ideal for delivering such items and any other soft and flat items that cannot easily be crushed, such as cases, a deck of playing cards, and smaller board games.
Apparel: Poly mailers are ideal for shirts, footwear, and jeans that cannot be crushed in transit. Cloth and fabric-based products such as bedding and yarn can also be shipped. When shipping clothing with delicate beading and jewellery, it is best to utilise bubble mailers to prevent damage.
Books and printed media: Bubble mailers are ideal for transporting books and printed media because they provide additional padding to avoid rips and dents.
Health and beauty products are a great way to distribute health, beauty, and wellness products. Vitamins, supplements, cosmetics, and nutrition goods are popular in this area. These products can be safely transported using poly mailers as long as they are encased in sturdy materials.
The most commonly used poly mailers are unsustainable since they are derived from crude oil, a non-renewable resource. However, if recycled, they are more sustainable since businesses may utilise them to make more items without producing more plastic from virgin crude oil.
Additionally, poly mailers are made from a durable material that will ensure products last for an extended period. This will result in less waste entering the environment as it may be reused for long periods, requiring fewer materials for continuous manufacture. Nonetheless, these plastic shipping envelopes can be hazardous to the environment, especially in high quantities. So, the following are some ways to recycle and reuse poly mailers.
Most poly-mailers, made of a material called polyethene, can be recycled. However, recycling polythene products like shopping bags and eco-friendly poly mailers is more complex than recycling cardboard boxes. It is also vital for wholesale poly mailers to be disposed of properly to avoid landfills. Poly mailers can be dropped off at local grocery and retail stores with plastic grocery bags and poly mailer collection bins.
In Singapore, the drop-off point is near the SingPost POPStation or Central Plaza near Tampines Hub. Before dropping off used mail packaging, removing any private information on mailing labels is crucial. This can be done by using alcohol or nail polish remover to remove permanent marker ink or by writing over private information with a dry-erase marker before wiping it off. All old logos and shipping labels should also be covered or blacked out.
Poly mailers are reusable. However, the adhesive strip on the poly mailer cannot be reused. The envelope must also be carefully opened so that its resealing ability is not compromised. Instead of breaking the seal, delicately cut open the top of the envelope. When reusing, fold the top over and secure the poly mailer with packaging tape. The disadvantage is that poly mailers cannot be reused indefinitely because there are limited times they can be cut open and resealed with tape.
From the basic protection offered by standard polymailers to the enhanced cushioning of bubble variants, the convenience of returnable options, and the distinctiveness of customised versions, polymailers have carved a niche for themselves in the packaging industry.
