    1. Advantage of paper

    - Made from durable, waterproof natural kraft paper. 100% curbside recyclable, completely biodegradable in soil.

    - An eco-friendly alternative to traditional poly mailer.

    - Natural brown kraft paper offers excellent surface for custom printing and complement your environmentally friendly brand values.

    - Non-toxic, water-based ink provides more positive environmental value.

    2. Bag shape features

    - Convenient peel & seal closure for speed and ease of packing.

    - Expandable base and side gussets allow more capacity - as bigger opening can fit more/larger items. Its flat bottom other than welded seams allows the bag to stand, as well as sides and bottom being expandable helps all bags stack flat but still can accommodate everything you need to put in.

    - Volume and weight reduction as it is light and thin, without cushioning layers.
