Custom Mylar Bags

Honghai Packaging has been manufacturing flexible packaging since 1996. We provide OEM and ODM services covering pouch structure, size, printing, surface finish and functional accessories. Our capabilities include digital and gravure printing, multilayer barrier materials and custom pouch production for both new product launches and repeat bulk orders.

Our custom Mylar bags can be developed for legally marketed cannabis flower, pre-rolls, edibles, hemp-derived products and other regulated goods where permitted by local law. They are also suitable for food, supplements, herbs, coffee, snacks and other products requiring moisture, oxygen, light or odor protection.

Available options include stand-up pouches, three-side-seal bags, flat pouches, flat-bottom bags, shaped pouches and pre-made bags with zippers. Features such as tear notches, hang holes and different bottom gussets can be added according to the filling method and retail presentation.

Although “Mylar bag” is a common market term, the final pouch normally uses a customized multilayer film structure. Available options include PET/PE, PET/VMPET/PE, PET/AL/PE and structures containing nylon for additional strength.

The material is selected according to the product’s moisture sensitivity, odor-control requirements, light sensitivity, shelf-life target and transportation conditions.

High-barrier films and properly sealed closures can significantly reduce odor transmission, but performance depends on the material structure, zipper, seal quality and product characteristics.

For products with strong aromas, we generally recommend metallized or aluminum-foil barrier structures. Product-specific storage and odor testing should be completed before full-scale production.

Child-resistant zipper options are available for suitable pouch designs. However, adding a child-resistant zipper does not automatically make every finished package legally compliant.

Compliance should be evaluated using the complete package, including the pouch, zipper, dimensions, film thickness and opening method. In the United States, child-resistant packaging standards use child and adult testing procedures under 16 CFR Part 1700, while individual states may impose additional cannabis-specific requirements.

Requirements depend on the destination market, product category and whether the package is single-use or reclosable. For example, California requires cannabis goods to be sold in child-resistant packaging, and responsibility for meeting the requirement rests with the licensed business packaging the product.

Yes. Depending on the pouch design, tamper-evident protection may include a heat-sealed top section above the zipper, tear-off opening area or another visible first-opening feature.

Some jurisdictions specifically require packaging to provide reasonable assurance that it has not been opened before reaching the customer. The selected feature should therefore be reviewed against the applicable local regulations.

Transparent windows can be added for products and markets that permit product visibility. However, windows are not suitable for every regulated product.

Some jurisdictions require the immediate cannabis container to be opaque or translucent. For example, Canada applies opacity, contamination protection, dryness, tamper-evidence and child-resistant requirements to relevant cannabis packaging. Always confirm local rules before approving a window design.

Yes. We can customize the width, height, bottom gusset, seal width and film thickness for different filling weights and product densities.

Small retail packs, multi-use pouches and larger formats can be developed, but the final size must leave sufficient room for sealing, labeling and any legally required warnings. Customers should also confirm whether their market limits the permitted quantity per package.

Yes. We support custom logos, product names, flavor or strain identification, variable SKU designs, barcodes, QR codes, batch areas and regulatory information panels.

The artwork should reserve sufficient space for mandatory warnings, universal symbols, net quantity, licence information and other market-specific content. Final label text and legal approval remain the customer’s responsibility. California, for example, separates required information between the primary and informational label panels.

Yes. Packaging must not be designed in a way that violates local advertising, youth-protection, trademark or product-presentation rules.

Customers should avoid cartoons, child-oriented characters and designs that imitate popular candy, snack or beverage brands. California prohibits cannabis products that are attractive to children, and the FDA has warned about THC products packaged to resemble commonly consumed branded foods.

Our minimum order quantity is 1,000 pieces per size and design.

Artwork preparation normally takes approximately 1–3 days. After the artwork, pouch structure and specifications are approved, standard production generally takes around 2–4 weeks. The final schedule depends on the printing method, number of designs, bag structure and order quantity.
