Side Gusset Bags FAQS
-+What types of products are best suited for side gusset bags?
Side gusset bags are widely used in the food and beverage, agriculture, pharmaceutical, and chemical industries. They are ideal for packaging products like coffee, tea, pet food, dried fruits, powders, and granules.
-+How do you pack and ship the bags?
We bulk-pack the bags in sturdy corrugated cartons, then palletize and securely wrap them in shrink film to ensure safe transit. To protect the bags and optimize shipping space, we select the most suitable carton size for each order, unless you have custom packaging requirements.
-+How are side gusset bags sealed to keep products fresh?
You can easily heat-seal the top to make the bag airtight, which locks in the aroma and extends shelf life. We supply them with an open top so you can fill and seal them on your own production line.
-+Can I add degassing valves or tin ties to the bags?
Yes, absolutely. Degassing valves are often used for coffee or fresh produce to release gas while keeping air out, and tin ties can be attached to the opening for easy resealing. Just let us know what you need.
