What is a Laminate?

Laminated packaging is the procedure by which two or more flexible packaging films and or paper are layered together using an agent that bonds the layers permanently together. A number of substrates can adhere together and may consist of film, paper, or metal foil in varying configurations.

How is Laminate Used?

Here are the most common laminate products we make here at Zekun Packaging.  If your products have specific requirements we can work with you to design a laminate combination that meets your production needs.

BOPP stands for biaxially-oriented polypropylene. It’s a variant of polypropylene (PP). Polypropylene a thermoplastic polymer, alternately known as polypropene. It’s an ideal printing surface .

For food, BOPP offers significant advantages. It’s non-toxic. The material’s also resistant to solvents and acids. Many food and beverage items, such as those containing tomatoes, citrus, or coffee, are quite acidic.

BOPP properties including ruggedness, fatigue resistance, moisture resistance, very low toxicity, flexible finishing options, as well a controllable transparency (manufacturers can make BOPP clear, nontransparent, or any translucency in between).


Nylon (Polyamide, PA) is a plastic made up of polyamide resins.

Often used in vacuum and sharp-pointed goods packaging; and because of its low temperature resistance, high temperature, so it can be used as frozen products, high temperature cooking products packaging printing materials;

PA Materials for use in vacuum are materials that show very low rates of outgassing in vacuum and, where applicable, are tolerant to bake-out temperatures.


CPP (Cast Unoriented Polypropylene) is a cost-effective, low density, high-performance transparent cast polypropylene film.

These characteristics make this plastic good for the medical, food packaging, and textile industries to name a few.

CPP films are often seen as having optical clarity, high gloss, good seal strength, and machinability, and are resistant to tears and punctures.


polyethylene (PE), light, versatile synthetic resin made from the polymerization of ethylene. Polyethylene is a member of the important family of polyolefin resins.

 It is the most widely used plastic in the world, being made into products ranging from clear food wrap and shopping bags to detergent bottles and automobile fuel tanks.

It has desirable physical properties such as high ductility, high impact strength, and very great chemical resistance. There are different types of polyethylene that are used in different applications.


A kind of metal aluminum directly caldered into a thin sheet, because the aluminum texture is soft, ductility, has a silver white luster, if the extended sheet, with sodium silicate and other substances mounted on offset paper to make aluminum foil, can also be printed.

Thousands of tons of aluminum foil are used around the world to protect and package food, cosmetics, and chemicals.

Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air tightness, shading, abrasion resistance, fragrance preservation, non-toxic and tasteless


Metallized PET Film ( VMPET Film) is a polyester film coated with a thin layer of aluminum by a vacuum aluminizing process.

 It can be widely used for Food packaging, including snacks, cookies, coffee, milk powder, tea, and so on, medicine packaging, decorative material, and also for specialty applications including insulation and electronics. It is normally used as the middle layer of lamination film.

 It offers the glossy metallic appearance of an aluminum foil at a reduced weight and cost and has excellent gas and light barrier properties, good moisture resistance, heat resistance, and good film stiffness.

Kraft Paper

Kraft paper is made from at least 80% sulfate wood pulp. It is course and exceptionally strong, making it well suited for a packaging substrate.

As a plastic hazard free paper in paper sacks for cement, food, chemicals, consumer goods, flour bags etc.

Normal kraft paper is strong and relatively coarse. It has high tensile strength. The grammage is normally 40–135 g/m2.
