What Are Custom Mylar Heat Seal Bags?
Flexible packaging pouches made from Mylar—a durable polyester film known for its exceptional barrier properties—are known as Custom Mylar Heat Seal Bags. These bags are sealed using a heat sealer, which fuses the opening shut to create an airtight, tamper-evident seal. The bags are fully customizable in size, shape, thickness, and printing design, allowing brands to tailor packaging specifically to their products. Heat sealing ensures maximum product protection and shelf life, making these bags suitable for everything from food and supplements to electronics and cannabis.
Why Choose Heat Seal Bags Made From Mylar?
Mylar is a biaxially-oriented polyethylene terephthalate (BoPET) film that is popular in packaging for its strength and excellent barrier properties. These include:
- Resistance to moisture, oxygen, and light, which protects product freshness and quality.
- Superior puncture and tear resistance compared to standard plastic films.
- Chemical inertness, meaning it doesn’t react with packaged products.
- High durability, which reduces damage during shipping and handling.
When heat sealed, Mylar bags provide an airtight barrier that preserves product freshness, protects against contamination, and helps comply with safety regulations.
