🌱 350x450x120 e-Green Block Bottom Paper Mailer with Single-Sided Print

Are you looking for an eco-friendly and eye-catching solution for shipping larger products? The e-Green Paper Mailer (350×450×120 mm) is the perfect alternative to standard poly mailers, combining sturdy kraft paper with the option of your own single-color print. Choose natural materials and highlight your brand's image as one committed to sustainability!

📦 What is the Block Bottom design?

The e-Green Paper Mailer features a Block Bottom construction — a flat, rectangular expansion that increases the packaging's capacity and stability. Thanks to this, it can safely hold larger items and maintain its shape during transport.

• 🧱 Stable, flat bottom: the bag stands securely and keeps its form even with heavier contents.
• 📐 Larger packing space: the rectangular expansion (40 mm) increases capacity and facilitates the packing of larger dimension products.
• 🎁 Aesthetic packaging: perfect for gift sets, cosmetics, accessories, books, and premium products.
• 🚚 Secure shipping: the stable base limits content movement and ensures better protection during transport.

🌟 Key advantages of the e-Green Paper Mailer

• ♻️ Ecology: made from certified kraft paper (FSC), which is renewable and easy to recycle – plastic-free with no micro-waste generation.
• 💪 Durable and safe: thick paper protects against crushing and abrasion, while the wide bottom (120 mm) and sides provide plenty of space for products.
• 🔐 Quick closing and opening: the mailer is equipped with a self-adhesive strip and a tear strip, allowing the recipient to easily open the parcel without damaging the contents.
• 🎨 Single-sided and single-color print: in the Pantone palette. Personalize the packaging with your logo, slogan, or graphics to stand out from the competition and build a unique unboxing experience.
• 💡 Premium aesthetics: the natural texture of kraft paper immediately grabs attention and highlights your brand's commitment to caring for the environment.

• 🖼️ File format: vector formats are preferred (AI, EPS, PDF).

• 🖊️ Raster element resolution: 300 dpi.
• ✂️ Bleeds and safety margins: leave approx. 2–3 mm bleed and a 5 mm margin from the cut and crease lines.

🤔 e-Green Paper Mailer vs. Poly Mailer – key advantages

• 🌍 Eco-friendly: kraft paper is biodegradable and easy to recycle, whereas plastic film (LDPE) takes hundreds of years to decompose and often ends up as difficult-to-recycle waste.
• 🛡 Solid protection: thick paper effectively protects against abrasions and tears, while the adhesive strip and tear strip make closing and opening the shipment easy. Poly mailers are water-resistant but typically have only one adhesive strip, making reuse or returns difficult.
• 💼 Appearance and brand image: the e-Green Paper Mailer is associated with an eco-conscious approach and premium quality, positively influencing brand perception. Plastic packaging does not communicate an eco-friendly character – even with a good print.
• ♻️ Easy waste segregation: the customer can dispose of the used envelope in a paper recycling bin. Plastic envelopes require special collection and, in practice, often end up in mixed waste.

📏 Format and construction of the e-Green Paper Mailer (350×450×120 mm)

With dimensions of 350×450×120 mm, you gain the ideal solution for shipments requiring significant width, height, and depth. The expandable sides allow for the secure placement of larger or bulkier items, minimizing the risk of creases or damage.

Kraft paper provides a natural shield against abrasions, while solid folds and strong adhesive ensure stability during transport. Additionally, the tear strip allows the recipient to open the package quickly and aesthetically, while the adhesive strip guarantees efficient sealing without the need for additional tape.

📦 Application in domestic and international shipments

• 🇵🇱 Domestic courier and locker shipments: the larger format enables packing bulkier products (e.g., clothes, footwear, textiles), and the paper construction lowers shipping costs compared to cardboard boxes.
• 🌍 International shipping: lighter envelope weight means lower carrier rates, and the paper material facilitates recycling abroad as well.
• 🔒 Extra protection: for exceptionally delicate goods, eco-friendly fillers (e.g., tissue paper, cardboard) can be used – the mailer will still maintain its compact character.

Unlike poly mailers, paper shipping bags have lower water resistance, so for difficult weather conditions, consider additional moisture protection. Nevertheless, for most standard shipments – especially bulkier ones – this solution is sufficient and much more ecological.

💼 Who is the e-Green Paper Mailer for?

• Online stores, premium brands: stand out with eco-packaging and highlight your care for the environment from the very first contact with the package.
• Companies developing their own branding: single-color print (Pantone) allows you to present your logo, slogan, or graphics in an eco-friendly spirit.
• Boutiques and concept stores: emphasize the unique character of your products by offering customers a top-level unboxing experience.
• Marketing agencies, print shops: convenient for creating individual designs for advertising campaigns or events.

💲 Economical and ecological in one

• 🌍 Plastic reduction: you give up poly mailers in favor of a biodegradable and easily processable raw material.
• 🔄 Shorter packing time: a ready-to-use envelope with a peel-and-seal strip and tear strip significantly speeds up order fulfillment.
• ♻️ Simple recycling: the recipient can throw the used envelope into the paper bin, supporting the circular economy.
