Put simply, a flat-bottom pouch is a five-sided, free-standing pouch with a flat, rectangular base. It has material for greater space and strength, known as gussets, on both the left and right side of the pouch, with a fastener on top. Most flat bottom pouches are made with kraft paper, aluminium, or LDPE. Some will combine two or more layers for added protection or aesthetic purposes. For example, coffee roasters that want to communicate a rustic look may choose kraft paper on the outside with an aluminium foil interior, which is an effective barrier against light, moisture, and oxygen. Specialty coffee roasters can also choose to include additional features to maximise freshness and aroma, such as resealable zippers or degassing valves. Thanks to their versatility and large printable surfaces, flat bottom pouches are popular among those with a strong brand identity. They can be customised with different finishes, colours, and designs, which can help roasters connect with customers. Our premium flat-bottom bags are food-safe and sealable. The tear notch also makes opening the bag much easier. The side gusset and the block bottom allow the bag to hold a higher volume than comparable bags on the market. The flat bottom allows the bag to stand very well even when unfilled, making this bag particularly suitable for semi-automatic and fully automatic filling.Transportation: Ocean,Express,Air Payment Type: L/C,T/T,D/P,D/A
