Known as “Bubble Mailer,” this packaging material is made up of polyethylene film (paper) and bubbles. Film cutting is the primary step in processing HDPE or LDPE bubble film, and a specialized bag production equipment for bubble film is used to make and process the bags (hot drying and hot cutting bag making machine).
In this piece, we’ll take a look at what a bubble mailer is, what it’s used for, and the materials and methods involved in making them.
1. Traits of a bubble mailer:
Because there is air trapped in the bubble film’s central layer, the bubble bag is lightweight, flexible, shockproof, waterproof, moisture resistant, corrosion resistant, and compression resistant. Resistant to the Effects of Shock, Compression, and Elasticity Protection against water, humidity, and corrosion.
2. Bubble mailers have a wide variety of uses and applications.
In the modern day, wholesale bubble mailers have become a popular kind of flexible packaging. The countless tiny bubbles in bubble film are used to cushion and preserve delicate items during logistics and transit. These items include plastic, metal, ceramic, glass, electrical, handicrafts, domestic appliances, cooking utensils, precise instruments, and many more.
The premise is that air is included in the polyethylene film to form air bubbles to shield the object from impact, keeping it safe even when shaken. The film also acts as thermal insulation, making it useful for a wide variety of applications.
3. Bubble mailers are categorized as:
The three types of bubble mailers are as follows. What follows is a list of For starters, there’s the kraft bubble mailer, the co-extruded bubble mailer, the pearlescent bubble mailer, the pearlescent matte bubble mailer, the metallic bubble mailer, and the clear bubble mailer.
4. Bubble mailer dimensions:
Facing film (paper) thickness in a bubble mailer shifts based on the item’s weight. Sizes range from 2mil to 5mil and beyond. It’s possible to find bubbles with a diameter of 7 mm, 8 mm, 9 mm, 10 mm, etc., and a height of 3 mm, 5 mm, 8 mm, 10 mm, etc. The bubble mailer’s gramme weight is affected by both the bubbles’ size and the thickness of the face film (paper). Popular weights range from 90 to 200 grams.
- Calculate the bubble mailer’s length as follows: length of item + height + 2cm
- The bubble mailer’s width should be equal to the sum of the item’s width, height, and 2 centimeters.
- Standard bubble mailer envelopes have a 5cm wide flap.
Conclusion:
A bubble mailer is a flexible packaging material made up of polyethylene film (paper) and air. Film cutting is the primary step in processing HDPE or LDPE bubble film. Bubble mailers are lightweight, flexible, shockproof, waterproof, moisture resistant, corrosion resistant, and compression resistant. The three types of bubble mailers are as follows: Co-extruded, pearlescent and metallic. Sizes range from 2mil to 5mil and beyond. Gramme weight is affected by both the bubbles’ size and the thickness of the face film (paper).
