HSQY Biaxially Oriented Polyester Packaging Film

BOPET Packaging Film for Printing and Lamination

HSQY BOPET packaging film is a biaxially oriented polyester film designed for flexible packaging, printing, lamination and converting applications. Biaxial orientation provides a useful combination of tensile strength, stiffness, dimensional stability, clarity and surface consistency for high-speed packaging processes.

For printed flexible packaging, BOPET is commonly used as the outer structural and printable web of a laminate. It can provide a glossy or application-specific optical appearance while supporting reverse printing, adhesive lamination and subsequent conversion into pouches, sachets, wrappers and other packaging formats.

HSQY currently supplies BOPET film in thicknesses from 12μm to 75μm, with customized roll widths and clear, natural, hazy or colored options. Available surface configurations listed for this product include print-treated, slip-treated, hardcoat and untreated versions.

Printing, lamination, coefficient of friction, haze, shrinkage, treatment level, heat-sealing and barrier requirements should be specified separately for the intended packaging structure. Standard BOPET should not automatically be treated as a heat-sealable or high-barrier finished package without the appropriate coating, laminate or functional layer.

What Is BOPET Packaging Film?

BOPET stands for biaxially oriented polyethylene terephthalate. During production, PET film is stretched in both the machine direction and transverse direction. This orientation improves mechanical strength, stiffness and dimensional stability compared with unoriented polyester film.

In flexible packaging, BOPET is frequently used as the outer web of a laminated packaging structure. Its role can include carrying printed graphics, providing mechanical strength, improving package stiffness and protecting the printed layer when reverse printing and lamination are used.

The final package normally combines BOPET with another functional material according to the required sealing, moisture-barrier, oxygen-barrier or puncture-performance target. Examples can include PE, CPP, metallized films, aluminum foil or other application-specific layers.

BOPET Film Packaging Applications

BOPET Packaging Film Specifications

The following table retains the current HSQY product specifications. Final guaranteed values for treatment level, haze, gloss, shrinkage, tensile properties, coefficient of friction and other technical parameters should be confirmed in the approved technical data sheet for the selected grade.

Why BOPET Is Used in Flexible Packaging

High Mechanical Strength

Biaxial orientation provides high tensile strength and useful resistance to stretching during printing, lamination, slitting and packaging conversion.

Good Dimensional Stability

Dimensional stability helps maintain web control and printing registration during high-speed converting. Actual thermal shrinkage should be specified when the application is sensitive to heat.

Clear and Glossy Appearance

Clear BOPET can provide high product visibility and a glossy appearance for printed flexible packaging. Hazy and application-specific optical grades are also listed within the current HSQY range.

Printable Surface Options

Printing-grade BOPET can be supplied with a treated surface to improve ink or coating adhesion. Printing performance depends on surface treatment, treatment retention, ink chemistry and printing conditions.

Suitable for Laminated Packaging

BOPET is commonly laminated with sealant, barrier or structural layers to build packaging structures with the required sealing, moisture resistance, oxygen barrier and puncture performance.

Good Web Handling

Appropriate stiffness, surface roughness and slip properties help BOPET run through printing, lamination and packaging equipment. Coefficient of friction should be specified where machine performance is critical.

Print-Treated BOPET Film

A print-treated BOPET surface is designed to improve the adhesion of compatible inks, coatings or adhesives. Corona treatment or another application-specific treatment may be used depending on the selected film grade.

Buyers should specify which side of the film needs treatment and whether the film will be surface printed or reverse printed before lamination.

Do not specify only “printable BOPET.” A complete purchase specification should include the printing process, ink system, required surface energy, treatment side and any required treatment-retention period.

BOPET Film for Reverse Printing and Lamination

Reverse printing is commonly used in flexible packaging because the graphics are printed on the inside surface of the outer BOPET web and then protected by the laminate structure.

This structure can help protect graphics from abrasion and handling while maintaining a clean external film surface.

Lamination performance depends on BOPET surface treatment, adhesive chemistry, coating weight, curing conditions and the second web. Bond strength should be verified using the complete packaging structure.

Typical BOPET Flexible Packaging Structures

These are general packaging concepts rather than guaranteed HSQY laminate constructions. The final structure should be selected according to the packed product, filling process, barrier target, heat-sealing requirements and converting equipment.

BOPET Packaging Film Applications

Snack Packaging

Printed BOPET can be used as an outer laminate web for snack-food bags where graphics, stiffness and high-speed converting performance are important.

Candy and Confectionery Packaging

Clear and printed BOPET films can be used in confectionery packaging structures for candy, chocolates and other packaged sweets when combined with appropriate sealing and barrier layers.

Dry Food Packaging

BOPET laminates can be evaluated for nuts, dried fruits, cereals, bakery ingredients and other dry foods according to the required moisture and oxygen protection.

Printed Pouches and Sachets

BOPET can provide the printed outer web in laminated stand-up pouches, three-side-seal pouches and sachets when paired with suitable inner layers.

Labels and Graphic Packaging

Selected polyester films can also serve as printable label, overlamination or graphic substrates where dimensional stability and surface quality are important.

Industrial Flexible Packaging

BOPET can be used as a structural layer in industrial laminates and protective packaging where the complete material structure is selected for the required mechanical and barrier performance.

Standard BOPET Is Not Automatically Heat Sealable

Standard packaging-grade BOPET is normally selected for mechanical strength, printing, optical properties and lamination. It should not automatically be treated as the heat-sealing layer of a flexible package.

When direct heat sealing is required, buyers should specify a dedicated heat-sealable polyester film or laminate the BOPET to a compatible sealant layer such as an application-specific PE or CPP structure.

Seal-initiation temperature, hot tack and final seal strength depend on the actual sealing layer and should not be inferred from the BOPET outer web alone.

BOPET Barrier Performance

BOPET provides useful general protection in flexible packaging, but standard clear BOPET should not automatically be marketed as an ultra-high oxygen- or moisture-barrier film.

If the packaged product requires a defined OTR or WVTR, the buyer should specify the target value and test conditions. A metallized, coated or multilayer high-barrier structure may be required depending on the shelf-life objective.

Shelf life should be validated using the complete printed and laminated package rather than being predicted from the BOPET layer alone.

BOPET Film Technical Parameters Buyers Should Specify

How to Choose BOPET Packaging Film

1. Define the Final Packaging Application

Specify whether the film will be used for snack packaging, candy wrapping, pouches, sachets, labels, industrial laminates or another converting application.

2. Select the Required Thickness

HSQY currently lists 12–75μm. The correct gauge depends on stiffness, yield, laminate structure, converting speed and finished-package requirements.

3. Define the Printing Process

Provide the printing process, ink type, number of colors, printing side and whether reverse printing is required.

4. Confirm Surface Treatment

Specify whether one side or both sides require treatment and provide the required surface-energy value when known.

5. Define the Laminate Structure

Tell HSQY which film or foil will be laminated to the BOPET and which adhesive or converting process is used.

6. Specify Optical Requirements

Confirm clear, natural, hazy or colored appearance and provide target haze, gloss or approved reference samples when visual consistency is important.

7. Confirm Slip and COF Requirements

For high-speed packaging lines, coefficient of friction can directly affect web feeding, bag forming, winding and machine stability.

8. Confirm Barrier and Heat-Seal Requirements Separately

If oxygen barrier, moisture barrier, metallization or direct heat sealing is required, include these functions in the specification so the correct BOPET grade or laminate structure can be selected.
