Materials
  1. Rl

    Recycled LDPE

    Recycled LDPE is low-density polyethylene made from recycled feedstock, making it a more sustainable alternative to virgin LDPE. Due to the contents of recycled plastic, these mailer bags will have some small white flecks on their surface.
  2. Vl

    Virgin LDPE

    Virgin LDPE is low-density polyethylene (LDPE) made from virgin raw materials like crude oil. Virgin LDPE has a higher carbon footprint than recycled LDPE.
  3. M

    Masterbatch

    Masterbatches are mixtures of additives or pigments that are used to colour PCR plastic film. Sourceful mailer bags use white masterbatch (outer layer) and black masterbatch (inner layer). Masterbatch is often made with virgin materials.
  4. Sp

    Single peel & seal

    One strip of adhesive covered with PET backing paper. A single peel & seal makes fulfilment fast and helps make your packaging tamper-proof. Adding a peel & seal has minimal impact on your carbon footprint.
  5. Dp

    Double peel & seal

    Two strips of adhesive covered with PET backing paper. A double peel & seal makes fulfilment fast and returns easy for your customers. Adding a peel & seal has minimal impact on your carbon footprint.
  6. Si

    Solvent-based inks

    Solvent-based inks use solvents such as propyl acetate as their primary base. Commonly used for gravure printing because they dry quickly and allow for high-speed printing. Solvent-based inks offer a high-quality print finish but do have a higher carbon footprint than water or vegetable-based inks.

Supply chain assurance

A resilient, responsible supply chain

Certifications

We validate all supplier claims and third-party certifications such as ISO, BRC and FSC. And we ensure suppliers adhere to UK and EU laws on chemicals and product components, like UK REACH. This allows businesses to confidently buy high-quality products that align with a net-zero trajectory.

Our recycled post-consumer polyethylene supply chain is certified to the Global Recycled Standard (GRS). The Global Recycled Standard verifies the percentage of recycled content and tracks it from the source to the final product.

Vetted suppliers

We visit and vet every supplier we work with. We use our code of conduct to do this, which defines what we consider to be ethical working conditions. To work with Sourceful, suppliers and their manufacturing sites must meet this code. We then review their practices every year.

Quality control

Every order from our suppliers undergoes a quality inspection process before it’s shipped. Any order that fails quality inspection is returned to the manufacturer or reproduced immediately.

For orders manufactured internationally (outside the UK) we follow the Acceptable Quality Limit (AQL) method defined by ISO standards in ISO 2859 - 1.

For orders manufactured domestically (inside the UK), our suppliers perform the quality inspection process which we then verify through spot checks throughout the year.
