Your packaging film should do more than protect the product – it should run reliably on your equipment.

PACKMIC is an OEM flexible packaging manufacturer in Shanghai, China, supplying custom printed rollstock films and premade pouches engineered around your product, package format and filling line. We support vertical form-fill-seal (VFFS), horizontal form-fill-seal (HFFS) and flow-wrap equipment, sachet and stick-pack lines, premade-pouch filling machines, and thermoform-fill-seal applications.

From film structure and sealant selection to roll dimensions, coefficient of friction and print registration, each specification is developed to support smooth feeding, forming, filling, sealing and cutting on automatic packaging equipment.

Packaging Matched to Your Machine – Not Only Your Artwork

Automatic packing lines can be sensitive to film stiffness, thickness, friction, seal-initiation temperature, hot tack, web tension and repeat accuracy. A film may look correct but still cause slipping, wrinkles, weak seals, cut-off errors or unnecessary downtime if these parameters are not matched to the equipment.

Before recommending a structure, PACKMIC reviews the product, filling process, pack style, machine model and operating conditions. This allows us to develop a practical OEM packaging specification instead of offering a one-size-fits-all laminate.

Automatic Packaging Systems We Support

Final compatibility depends on the exact machine, jaw design, filling speed, product and processing conditions. A production-line trial is recommended before commercial approval.

What We Customize for Stable Automatic Packing

Film structure and barrier

• • Laminate or mono-material structure selected for moisture, oxygen, aroma, grease, light and puncture protection.
• • Thickness and stiffness adjusted for the product weight, bag size, forming method and handling requirements.
• • Options for frozen, chilled, microwave and retort applications, subject to end-use validation.
• • Seal-initiation temperature, operating seal window, hot tack and final seal strength.
• • Coefficient of friction, film flatness, stiffness and heat resistance for stable feeding and tracking.
• • Sealant selection for fin seals, lap seals, transverse seals, peelable seals or high-integrity hermetic seals.
• • Finished web width, print repeat length, core inner diameter, maximum roll outer diameter and roll weight.
• • Unwind direction, print orientation, eye-mark position, splice requirements and roll edge alignment.
• • Tolerances reviewed against the customer’s machine specification and filling-line setup.
• 
• • Custom gravure or digital printing with matte, gloss, spot-varnish and metallic appearance options.
• • Registration marks, laser scoring, tear notches, perforation and other functional features where suitable.
• • Artwork and barcode review before production, followed by controlled printing, lamination and slitting.

Material and Performance Options

Depending on the product, shelf-life target and packing process, available structures may include PET/PE, BOPP/CPP, PET/CPP, PA/PE, metallized high-barrier laminates, aluminum-foil laminates, and recyclable mono-PE or mono-PP solutions. Transparent, white, metallized and foil-based appearances are available.

Food-contact and performance requirements are confirmed according to the packed product, processing conditions and destination market. The final structure should be validated with the real product and the customer’s production equipment.

Our OEM Development Process

CHARInformation Needed for an Accurate Recommendation

Why Choose PACKMIC?

Frequently Asked Questions

1. Can PACKMIC match packaging film to my existing automatic machine?

Yes. Please provide the machine brand and model, bag style, current film specification, web width, repeat length, core size, unwind direction, target speed and sealing conditions. We will review these details before recommending a structure.

2. What is the difference between VFFS and HFFS packaging film?

VFFS equipment forms a tube from rollstock film and fills the package vertically, which is widely used for snacks, powders, granules and many frozen products. HFFS or flow-wrap equipment moves film horizontally and forms a pack around individual or grouped products such as bars, bakery products and tortillas. Some horizontal pouch systems also produce sachets or shaped pouches for powders and liquids.

3. Do you supply premade pouches for automatic pouch-filling machines?

Yes. PACKMIC supplies stand-up pouches, zipper pouches, flat-bottom pouches, flat pouches and spout pouches. Pouch width, opening performance, stiffness, zipper or spout position and the top-seal area must match the filling machine.

4. Can you supply film for sachet and stick-pack machines?

Yes. We produce rollstock for powder, granule, liquid and gel sachets. Repeat accuracy, web flatness, sealing performance and easy-tear design are customized to the application.

5. Are films available for frozen, microwave or retort products?

Yes, suitable structures are available. The final recommendation depends on the product, temperature, time, filling method and shelf-life target, and must be validated through testing.

6. Can you supply recyclable films for automatic packing lines?

Recyclable mono-PE and mono-PP structures are available for suitable applications. Because these films may behave differently from conventional laminates, the structure and sealing conditions should be reviewed and tested on the intended machine.

7. Can you provide samples for a machine trial?

Yes. Stock material samples or customized trial material can be discussed based on the structure, print requirement and trial quantity. Testing with the real product and production line is the best way to confirm compatibility.

8. What is the minimum order quantity?

MOQ depends on the film structure, web width, print method, finished size and number of designs. Share your specifications and expected volume, and we will recommend the most suitable production option.
