Black Vacuum Packaging Film

Black Vacuum Packaging Film is a multilayer rollstock film for vacuum packaging applications requiring a defined black appearance and a Surlyn-based sealing interface. The film combines thermoformable polymer layers, a black functional layer, and a heat-sealing layer in one structure.

Thickness, width, layer construction, barrier configuration, and roll format are specified according to the package design and processing conditions. The black structure provides a consistent dark appearance for packaging formats where controlled product visibility is required.

Thermoformable Layers
The structural layers provide the material base required for forming the film into the specified package geometry. Film thickness is selected according to forming depth and package dimensions.
Black Functional Layer
The black layer establishes the visual appearance of the finished package. Color is controlled as part of the film construction rather than applied as a separate finished-package coating.
Surlyn Sealing Interface
The sealing layer provides the heat-sealing surface for compatible package constructions. Sealing conditions are matched to the film structure and mating material.

Thickness
80, 100, 125, and 150 μm options cover different package structures and forming requirements. Selection should consider cavity depth, package rigidity, and handling conditions.
Sealing Interface
The sealing surface must match the mating package material. Film selection should therefore be confirmed together with tray material and sealing conditions.
Width
Width should correspond to the package layout and production format. The required width is normally established from the finished package dimensions and material arrangement.
Barrier Structure
A barrier layer can be specified when oxygen or moisture transmission needs to be controlled. Barrier requirements should be defined before the final film structure is confirmed.

Meat Packaging
The black film structure suits vacuum-packed meat formats where a controlled dark package appearance is part of the packaging specification.
Food Products
The film can be specified for food vacuum packaging requiring a black surface, defined film structure, and compatible heat sealing.
Processed Foods
Suitable for selected processed food formats where package appearance, vacuum formation, and sealing construction are considered together.
Custom Formats
Final application selection depends on the product, package geometry, mating material, vacuum process, and required film construction.

Forming Depth
Cavity depth and package geometry should be reviewed when selecting film thickness. Deeper formats may require a different material specification from shallow packages.
Vacuum Cycle
Vacuum conditions should be established for the actual package format. Package geometry and film structure both influence the forming process.
Sealing Conditions
Temperature, pressure, and dwell time should be set according to the sealing interface and mating material combination.
Trial Verification
Production trials can verify forming, vacuum response, sealing behavior, and final package appearance before volume production.

Thickness Measurement
Film thickness is checked against the specified value during production to maintain consistency between production batches.
Color Inspection
The black appearance is inspected against the defined material specification to maintain visual consistency across the finished film.
Seal Evaluation
The sealing surface is evaluated according to the specified film construction and package material combination.
Roll Inspection
Finished rolls are checked for width, winding condition, identification, and external packaging before shipment.

Material Definition
Thickness, layer structure, black appearance, sealing interface, and barrier requirements are established before production.
Roll Configuration
Film width, roll length, winding direction, and core requirements can be specified according to the production format.
Batch Identification
Production information can be assigned to rolls or batches to support material identification and production records.
Shipment Preparation
Finished rolls are packed according to the agreed handling and transportation requirements, with roll identification maintained through shipment preparation.

Confirm Package Structure
Provide the tray or mating material, package dimensions, cavity depth, and vacuum packaging format.
Select Film Thickness
Match the thickness to forming depth, package rigidity, and production handling requirements.
Confirm Sealing Interface
Verify the Surlyn-based sealing surface against the mating material and intended sealing process.
Define Barrier Requirement
Specify the required oxygen or moisture barrier structure when controlled transmission is part of the package specification.
Confirm Roll Details
Provide width, roll length, winding direction, core size, and required quantity for quotation and production planning.
