Custom Mylar Bags with Zippers or Heat Seals

Another thing to consider is how the bag opens and closes.

, we offer both zipper and heat-seal options to fit your product type.

Smell-Proof Custom Mylar Bags vs. Regular Bags

If your product has a strong smell, such as herbs, spices, or cannabis, 

are the better choice. These bags lock in odors and keep the scent from escaping. They’re also a good choice for keeping products fresh and discreet.

Regular Mylar bags still offer good protection but may not completely trap strong scents. They’re more suitable for items like trail mix, protein powder, or dried fruit. 

can help you decide which bag works best based on what you’re selling.

Wholesale Custom Mylar Bags vs. Small Batch Orders

Your order size also matters. If you need a lot of bags, 

are the most cost-effective. Buying in bulk is a smart move for businesses that ship many products or have steady sales.

But if you're just starting out or trying a new design, a small batch order might be better. This way, you can test the market without spending too much. At 

, we support both big and small businesses by offering flexible order sizes.

Find the Perfect Custom Mylar Bag for Your Brand

Choosing the right custom Mylar bag depends on what you're selling, how customers will use it, and how much you want to spend. Whether you need printed designs, zipper closures, or smell-proof protection,
