Security Bag Sealing Tape for PE, HDPE & LDPE Bag Manufacturers
Hanksec manufactures tamper evident security bag tape for PE, HDPE and LDPE security bag production. It is supplied as a functional sealing component for security bag manufacturers, flexible-packaging converters and OEM projects—not as an ordinary finished-bag seal.
Available constructions include Level 1–6 project configurations with VOID / OPENED evidence, temperature-related response, water or solvent-sensitive functions, UV / covert verification, security cuts, serial numbers, barcodes, QR codes and custom jumbo-roll formats. Final functions are confirmed against the selected construction, bag film and production process.

Bag tape is an integrated sealing component for flexible security bags. For carton, parcel or rigid-package sealing, use the separate
Security Packing Tapes
category.
Step 1 — Select the Security Level
Choose the Right Security Bag Tape Configuration
Start with the tampering methods the finished bag must reveal. Hanksec uses Level 1–6 as product-configuration descriptors for project selection rather than as a universal industry grading standard. Exact functions should be confirmed against the selected construction and approved sample.
BASIC
Level 1
Visible VOID / OPENED evidence for basic tamper indication on compatible bag-film constructions.
ENHANCED
Levels 2–3
Enhanced configurations build beyond basic VOID evidence with selected additional response functions according to the approved project specification.
HIGH SECURITY
Levels 4–5
Multi-function configurations can combine VOID evidence with temperature-related, water / solvent-sensitive, UV or covert, security-cut and identification features, depending on the selected construction.
PROJECT SPECIFIC
Level 6 / Custom
Project-specific configurations can combine several tamper-response, authentication, traceability and converting requirements in one approved construction.
| Buying Question | Basic Security | Multi-Function Security | Project-Specific High Security |
|---|---|---|---|
| Visible opening evidence | VOID / OPENED response | VOID plus additional indicators | Multiple combined indicators |
| Attack-method detection | Peel / opening attempt | Peel plus selected temperature or water / solvent response | Combined tamper response with optional authentication / traceability |
| Typical application | Courier / document bags | Cash / deposit / evidence bags | High-security controlled programs |
| What to confirm | Bag film + VOID effect | Required functions + production process | Complete bag structure + qualification plan |
Step 2 — Select the Tamper Functions
Match Security Bag Tape to the Tampering Method
Select tamper-response features according to the manipulation methods that should leave detectable evidence. Authentication and traceability features should be specified separately because they support inspection and identification but do not by themselves prove that the closure was opened.
VOID / OPENED Evidence
Creates irreversible visual evidence when the bag-sealing area is peeled or opened.
Heat Response
Thermo-responsive features can help reveal attempts to weaken or manipulate the sealing area with heat.
Water / Solvent Response
Specified water- or solvent-sensitive elements can provide additional visible evidence when the closure is exposed to relevant liquid or chemical manipulation.
UV / Covert Verification
UV-visible or covert marks can support authentication and controlled inspection, but they do not by themselves prove that the closure was opened.
Die-Cut Security
Die-cut patterns can create irregular tearing or structural disruption when removal is attempted.
Serial / Barcode Traceability
Variable data can support identification, reconciliation and chain-of-custody workflows, but traceability should be distinguished from tamper evidence.
Step 3 — Match Bag Film & Production
Security Bag Tape Must Match the Bag Manufacturing Process
Bag-film type, sealing construction, converting temperature, liner, adhesive and machine handling all affect production stability. Final qualification should use the actual bag material and production process.
BAG FILM
PE / HDPE / LDPE
Confirm film structure, surface treatment and bonding conditions before approving the tape construction.
ADHESIVE
Bonding & Activation
Adhesive performance must support both production handling and the required tamper response after bag assembly.
LINER
Release & Process Stability
Liner construction should support converting, lamination, rewinding and dispensing without unstable release.
MACHINE FIT
Width, Winding & Jumbo Roll
Roll width, core, winding direction and jumbo-roll format should match the actual bag-making line.

Step 4 — Define the Commercial Specification
Security Bag Tape Specifications & Custom Options
For quotation and sample preparation, define the security function and the production specification together.
Security LevelBasic to multi-function project-specific constructions.
Hidden MessageVOID, OPENED or customized security text.
Functional OptionsTemperature-related tamper indication, water / solvent-sensitive response, UV / covert authentication, security cuts and project-specific features.
Bag FilmPE, HDPE, LDPE or project-specific flexible packaging film.
Variable DataSerial numbers, barcode or QR code where required.
DimensionsTape width and roll length matched to the bag design and machine.
Core / WindingSpecified according to the converting and dispensing process.
Supply FormatFinished rolls, slit rolls or jumbo-roll supply for manufacturers.
Step 5 — Sample & Production Qualification
OEM Security Bag Tape Manufacturing Support
Jumbo Roll & Converting Supply
For bag manufacturers and converters, define roll width, roll length, core, winding, liner, printing, security functions and the intended bag-making process before production.
Sample Qualification
Test the approved construction on the actual bag film. Confirm bonding, release, machine handling, VOID activation and all additional security functions before bulk production.
Before requesting samples: send the bag-film structure, target Hanksec security configuration, required tamper-response and authentication / traceability features, tape dimensions, roll format, machine / process information and estimated quantity. This gives the technical team enough information to recommend a suitable construction.
