HDPE poly mailers are sturdy and puncture-resistant, perfect for protecting items like electronics. HDPE has higher density, making it tougher with a higher melting point, but less flexible.[Click here to learn more.]
Knowledge You Want To Know About The Release Liners
There are three primary types of release liners for poly mailers: paper release liners, plastic release liners, and aluminum foil release liners, each offering distinct features tailored to your specific requirements..
Paper Release Liner: Paper release liners are eco-friendly and biodegradable, making them an environmentally responsible choice. They offer good printability, allowing easy customization with text and graphics, while remaining cost-effective.
Plastic Release Liner: Plastic release liners are known for their durability and versatility. They can be made from various plastics like polyethylene or polypropylene, making them suitable for diverse applications. However, their pricing varies depending on material type, thickness, and size.
Aluminum Foil Release Liner: Aluminum foil release liners combine a luxurious appearance with high-temperature resistance. They are visually appealing but tend to be more expensive compared to paper and some plastic options, making them suitable for specialized or premium applications.

How Custom Poly Mailers Are Made

Film Blowing: Film blowing is a plastic processing method where plastic particles are melted and inflated into a tubular film using high-pressure air. This film is then cooled and finalized. The film-blowing machine is critical for producing high-quality film packaging with excellent barrier properties and freshness preservation.
Printing: Poly mailer bags undergo high-quality printing using a specialized gravure press. This involves transferring the design onto a copper plate, ensuring precise ink application. The inked plate is then pressed onto the co-extruded film for printing.
Deflation and Heat Seal: The final step in creating poly mailer bags is bag cutting and bag making. The co-extruded film is laminated with an adhesive strip and then precisely cut and heat-sealed by the bag-making machine to create the poly mailer envelopes. The choice of hot melt adhesive is crucial for ensuring the bags’ strength and anti-counterfeiting features.

What Design File Shoule Be Prepared

File Format: Preferred formats: AI (Adobe Illustrator) or PDF for high-resolution artwork.
Resolution:Minimum of 300 DPI (dots per inch) to ensure sharp and clear prints.
Color Mode:Use CMYK color mode, which is best for four-color process printing. Avoid RGB mode to prevent color printing issues.
Fonts:Convert all text to outlines or include the specific fonts used to avoid font replacement issues.
Graphic Elements:All logos, photos, and icons should be high quality and correctly positioned. Provide necessary links and avoid using copyrighted images without permission.

How To Store Custom Poly Mailers

Keep Them Dry:
Ensure that poly mailers are stored in a dry environment, away from moisture and humidity. Humidity can make the bags sticky and difficult to handle, and it may even lead to mold growth.
Avoid Direct Sunlight:
Don’t expose poly mailers to direct sunlight, as UV rays can make the bags brittle and impact their strength and durability.
Control Temperature:
Aim to store your poly mailers in a controlled temperature environment. Extreme temperatures can have adverse effects on the polyethylene material.
Avoid Heavy Pressure:
Don’t place heavy objects on top of the poly mailers, as this can cause them to break or deform.
Stay Clear of Chemicals:
Prevent poly mailers from coming into contact with chemicals such as solvents, acids, or alkalis to avoid chemical reactions or damage to the material.

Factors That Influence Prices Of Custom Poly Mailers

Material Quality:
The quality of materials used impacts cost. Higher quality may mean higher costs but improved durability and features.
Size and Dimensions:
Larger or custom-sized mailers require more material and may have complex manufacturing, leading to higher costs.
Thickness and Strength:
Thicker and stronger mailers protect better but can be costlier due to increased material usage.
Quantity and Volume:
Bulk orders often offer lower per-unit prices due to economies of scale.
Custom printing, logos, or designs add costs due to printing and setup expenses.
