What are the popular flexible packaging types at present?
What is Flexible Packaging?
Flexible packaging refers to packaging that is made of one or more flexible materials (such as plastic film, paper, aluminum foil, non-woven fabric, etc.) and can change shape after filling or removing the contents. Simply put, it is soft, deformable, and lightweight packaging. We can see them everywhere in our lives:
What materials are flexible packaging made of?
The material provides the primary structure, strength and shape of the package.
For example, plastic films such as PE, PET, CPP, aluminum foil suitable for food and medicine packaging, and printable paper are the main materials for packaging bags.
What is the production process of flexible packaging?
1. Printing: Gravure printing and flexographic printing are commonly used to achieve high-quality, colorful patterns.
2. Composite: Combine films with different functions by adhesive (dry composite, solvent-free composite) or hot melt (extrusion composite) to form a multi-layer structure.
3. Curing: Allow the composite adhesive to fully react and cure to reach its final strength.
4. Slitting: Cut the wide composite material into the narrow width required by the customer.
5. Bag Making: Heat-sealing the film into various bag shapes (such as three-side seal bags, stand-up pouches, and zipper bags).
All packaging bags undergo these processing steps to become a complete product.
Characteristics of various flexible packaging bags
1.Stand Up Pouch
A stand-up pouch is a flexible packaging bag with a horizontal support structure at the bottom, which allows it to "stand" independently on the shelf after being filled with contents. It is a very popular and versatile form of modern packaging.
2.Spout Pouch
It is an advanced form of stand-up pouch with a fixed spout and usually a lid for easy pouring of liquid or powdered products.
3.Kraft Paper Bag
Bags made of kraft paper are natural and environmentally friendly. They range from simple shopping bags to multi-layer heavy-duty packaging bags.
4.Three Side Seal Bag
The most common flat bag type has heat-sealed edges on the left, right, and bottom, with the opening at the top. It is one of the simplest and most cost-effective bag types to manufacture.
5.Double Bottom Bag
It has the characteristics of food grade sterility, pressure resistance and explosion resistance, sealing, puncture resistance, drop resistance, not easy to break, no leakage, etc. It is made of composite materials and can be transparent with zippers or butterfly valves for easy opening and closing.
6.Bag in Box
A packaging system consisting of an inner bag of multi-layer composite film and an outer rigid carton. Usually equipped with a tap or valve for taking out the contents.
7.Roll Film
This is not a formed bag, but the raw material for making the bag - a roll of packaging film. It needs to be completed by an automatic packaging machine on the assembly line through a series of operations such as bag making, filling, and sealing.
Summarize
Flexible packaging is an important component of the modern packaging industry, permeating every aspect of life with its excellent functionality, convenience, and affordability. Currently, the industry is rapidly developing towards green, intelligent, and functional development. In the future, the packaging market will see the emergence of more distinctive packaging bags, which is exactly what we are constantly striving to do.
