What Is Mylar Heat Seal Bag?
Mylar heat seal bags are a type of packaging made from a special material called Mylar, which is a polyester film known for its strength and ability to block oxygen and moisture. These bags are designed to be sealed using heat, creating an airtight closure that helps keep the contents fresh and protected.
Features
- Excellent barrier properties: Mylar is highly effective at blocking oxygen, moisture, and light. This helps to preserve the freshness and quality of the contents inside, making them ideal for food storage and protecting sensitive items.
- Durable and strong: Mylar is a tough and tear-resistant material, ensuring the bags can withstand handling and transportation without damage. This makes them suitable for storing a variety of items, including heavy or bulky ones.
- Airtight seal: The heat-sealing process creates a strong and airtight closure, preventing air and moisture from entering the bag. This is crucial for long-term storage and maintaining the quality of the contents.

Artwork Preparation Guide
At BoxesGen, our Artwork Preparation Guide helps ensure your custom packaging design is print-ready for high-quality results. To get started, submit vector files (AI, EPS, or PDF) in CMYK color mode, with a 1/8 inch bleed and 300 DPI resolution. Convert all text to outlines and keep it at least 1/4 inch from the edges. Review your proof to ensure accuracy before submitting. Following these steps will guarantee your design is perfectly printed on your custom boxes.

Cut Line (Black Lines):
The cut line is the outline that marks where your custom packaging will be trimmed. It is typically represented by a solid black line in your artwork file.
Perforation (Dotted Black Lines):
Perforation lines, shown as dotted black lines, indicate where the box will have small, evenly spaced holes for easy tearing or separation. These are often used for tear-away sections.
Bleed Line (Green Lines):
The bleed line is the area extending beyond the cut line, usually marked with a green line in your artwork. Typically, a 1/8 inch (0.125") bleed is required to prevent any unwanted white borders.
Safety Margin (Dotted Green Lines):
The safety margin, marked by dotted green lines, is the area around the cut line where important elements (such as text, logos, or graphics) should be kept clear.
Crease Line (Red Lines)
The crease line, marked by red lines in your artwork, indicates where the box will be folded during production.
