Most of the brands make a mistake by thinking of packaging as just a bag. However, your packaging is a gateway between the product and your customers. It affects how you are going to present a product and what level of protection your product has. In this regard, custom mylar bags are the perfect option. But the perfect packaging is not all about look and material durability. There are two common factors that need to be considered when protecting and presenting the product. These two are the thickness and size of Mylars. To understand this better, let’s read the blog.
What Is A Mylar Bag?
Mylar bags are manufactured with a plastic material that undergoes a physical treatment. This treatment is known as bioxially oriented. The name Mylar is a trademark term that was first coined by the packaging company DuPont. Polyethylene terephthalate is the main material that is now used by several industries to pack their product to keep them protected from moisture and oxidation.
Mylars are highly flexible and have remarkable strength properties that make them ubiquitous in several industries. For the perfect thickness of the bag, a special unit, “mil.” is used. This is a perfect unit to measure the thickness of very thin items.
How Is Mylar Bag Thickness Measured?
Multilayer plastic layers are laminated to manufacture custom mylar bags wholesale. These multiple layers are laminated over a metal, which is usually aluminum. This layer enhances the protective ability of mylar. For the perfect thickness of the bag, a special unit, “mil,” is used. This is a perfect unit to measure the thickness of very thin items. One mil is equal to 1/1000 of an inch. Typical thicknesses of custom printed mylar bags are:
- 3.5–4.5 mil: Used for small bags and are ideal for short-term or lightweight packaging.
- 4.5–6.5 mil: Suitable for larger dimensions and items that need stronger protection.
- 7 mil and above: This thickness is used for long-term storage and high-value contents.
3.5 Mylar bag size is not considered highly durable. Bags with this thickness are unable to block oxygen and moisture. The thickness of mylar is more than protection. The different layers perform different functions. For instance:
- PET (Polyethylene Terephthalate): Adds strength and clarity.
- VMPET (Vacuum Metallized PET): Reflects light and blocks UV rays.
- PE (Polyethylene): This material makes the bag heat-sealable and flexible.
Why Aluminum Needs Support
Aluminum foil alone cannot be heat-sealed. That is why it is bonded with polyethylene or similar material that forms a functional barrier. Without the additional coatings, you cannot properly seal the bag, and the puncture resistance quality of the boxes will also be reduced.
Selecting The Thickness
When selecting custom mylar bags Canada, consider the type of food you are going to pack. Different foods have different requirements and different levels of protection. The general thickness based on the food type is as follows:
| Food Type | Thickness | Reason |
| Ground coffee | 4 mil | Powder protection |
| Coffee beans | 5 mil | Bulk resistance |
| Brown sugar | 4 mil | Moisture control |
| Pasta jerky | 7 mil | Long-term barrier |
| Salt sugar | 4 mil | Seals properly |
Thickness Guide
| Thickness Level | Use Case | Benefit |
| 4 mil | Snacks samples | Short-term use |
| 5 mil | Whole foods | Edge resistance |
| 7 mil | Emergency kits | Premium protection |
As a general rule, it is advisable to select a 4-mil Mylar if you require long-term protection. A thicker bag gives high-end puncture resistance and UV protection.
Selecting The Size Of The Mylars
Whether you are a grower or are running a dispensary, selecting the right size of the mylars is essential. The right size of the bag is not just essential for protecting the product; it is vital for presentation and shelf appeal. Specifically, if you are packing cannabis or any flower-based product, you have to make sure that the mylar bag sizes are precise.
| Quantity | Bag Size | Use Case |
| 1 Gram | 3×4 in | Compact buds |
| 1/8 oz | 3.5×5 in | Sleek flower |
| 1/4 oz | 4×6 in | Spacious fit |
| 1/2 oz | 5×8 in | Protect display |
| 1 oz | 6×9 in | Secure freshness |
| 1/4 lb | 8×10 in | Larger portions |
| 1/2 lb | 10×12 in | Bulk storage |
| 1 lb | 13×15 in | Maximum protection |
The sizes mentioned in the table are widely accepted and considered optimal for storage and presentation. The sizes and thickness of the bags go hand in hand. For instance, a 1-pound Mylar bag size is around 10×14 inches.
Why Consider Custom Mylar Bag Sizes?
Standard sizes of mylars are convenient and can be used by several industries. But custom bags give a competitive edge to the customers in both functionality and aesthetics. You can go custom because:
- Fit to Form: You can pack your product in bags with exact dimensions. This results in a cleaner and more professional finish.
- Save and Secure: A right-sized custom mylar bag minimizes empty space that can cause shifting of product during transit.
- Stand Out: The size of your bag, paired with custom designs, will create a striking appeal for your product and reinforce your brand identity.
- Efficient Use of Materials: Helps in the reduction of cost by avoiding the use of extra material.
