Labels Begone? The Possibilities of Direct Printing on PET Packaging

In a market where shelf space is precious and compliance demands precision, packaging design has to do more than hold your product—it has to hold attention. MedLock™ is helping licensed producers (LPs) simplify and elevate their packaging presentation through direct printing on PET containers, eliminating the need for traditional labels while improving efficiency, accuracy, and brand appeal.

Direct printing transforms packaging from a container into a communication tool—clear, compliant, and completely on-brand.

Why LPs Are Moving Away from Labels

Labels are often the weakest link in cannabis packaging. They can wrinkle, peel, fade, or misalign, causing rework and compliance issues. For products that require precise dosage, regulatory icons, or multilingual text, adhesive labels can also limit design flexibility.

Common problems with traditional labels:

• Adhesive failure due to oil or moisture contact

• Fading under UV exposure

• Misalignment during automated application

• Waste from roll misprints or machine errors

MedLock’s direct printing services solve these challenges by applying artwork, regulatory information, and branding directly to the container surface, ensuring a permanent, professional finish that never peels or fades.

The Advantages of Direct Printing

Direct printing offers a cleaner, faster, and more sustainable solution to cannabis packaging decoration. By integrating branding into the package itself, LPs save time on production while enhancing shelf appeal and regulatory accuracy.

Key advantages:

• Durable finish: Resistant to moisture, abrasion, and UV light.

• Permanent compliance text: Cannot be removed or damaged like adhesive labels.

• Improved sustainability: Eliminates label waste and adhesive materials.

• Reduced lead times: Printing is completed during the production process.

• High-impact branding: Crisp, consistent graphics across every unit.

For LPs managing multiple SKUs or compliance variations, direct printing also simplifies production by eliminating separate label inventories.

Printing Methods Tailored to Every Brand

MedLock offers several in-house printing technologies optimized for different artwork styles and production scales.

1. Pad Printing (1–2 Colours)

Ideal for simple logos, dosage indicators, or strain names on small containers and closures. The pad conforms to curved or irregular surfaces, delivering sharp, consistent graphics.

2. Screen Printing (Up to 4 Colours)

Best for bold, high-opacity designs or branding on darker PET and glass containers. Screen printing creates vibrant colour contrast and long-lasting durability.

3. Digital Wrap Printing (Full Colour)

A high-resolution, 360° print method capable of replicating photographic artwork and gradient designs. Perfect for premium lines or custom promotional SKUs.

4. Variable Data & QR Code Printing

For products requiring batch tracking, QR codes, or serialized compliance data, MedLock offers digital variable data printing to ensure traceability across production lots.

PET Packaging That’s Perfect for Printing

MedLock’s FDA-grade PET jars, bottles, and tubes provide a smooth, printable surface for direct artwork application. The high-clarity plastic ensures sharp, detailed graphics, while its impact-resistant nature maintains quality through filling, labeling, and transport.

Available product types for direct printing:

• PET Dried Flower Jars

• Extract and Oil Bottles (PET and Amber Glass)

• Packer Bottles for Edibles

• Pop-Top Tubes for Pre-Rolls

• Click-Lock™ Closures and Caps

Each container is produced under strict quality control, ensuring consistent surface tension for ink adhesion and colour accuracy.

Compliance Built Into the Design

Direct printing helps LPs maintain Health Canada compliance by embedding regulatory text and symbols directly onto the packaging substrate. This approach eliminates the risk of missing or misplaced warning labels, while maintaining full CR/TE certification.

Compliance benefits:

• Permanent display of THC icons and mandatory text

• Reduced risk of mislabeling or noncompliant packagin

• Easy integration of bilingual or variable information

• Documentation available for audit or verification purposes

With MedLock’s regulatory printing support, every package leaves the facility fully compliant and audit-ready.

Sustainability That Shows

Direct printing also contributes to MedLock’s zero-waste manufacturing philosophy. By eliminating adhesive labels, backing paper, and liner waste, LPs can significantly reduce their material footprint.

Combined with EcoPure® biodegradable and recyclable PET options, direct printing aligns visual branding with environmental responsibility.

Environmental benefits:

• Fewer consumables and packaging waste

• Energy-efficient print processes

• Compatible with biodegradable and recyclable substrates

• Supports circular economy goals without design trade-offs

Whether launching a craft cannabis line or scaling a national portfolio, MedLock’s direct print capabilities give every container a premium, retail-ready finish that lasts.

Benefits summary:
