Florida’s climate is known for its extremes—sweltering heat, intense humidity, and relentless sun exposure nearly year-round. While it’s great for beach days, it’s brutal on packaging.
For businesses shipping or storing products in Florida, traditional shrink packaging materials can struggle. Films that perform perfectly in cooler climates may soften, wrinkle, or even fail under Florida’s conditions—especially in unconditioned warehouses, delivery trucks, or outdoor loading areas.
That’s why Sun Packaging Technologies, Inc., headquartered in South Florida, has become the go-to expert in shrink packaging built for hot climates. With over 30 years of experience, Sun Packaging understands how Florida’s heat and humidity affect packaging performance—and how to solve those challenges with the right combination of film, equipment, and process optimization.
In most states, temperature fluctuations are minor. But in Florida, even the smallest packaging misstep can lead to major losses.
Here’s what local businesses often face:
Premature shrinkage: When films soften in transport or storage, they can partially shrink before application, making them unusable.
Seal failure: Moisture and heat can weaken sealing performance, leading to open edges or contamination.
Fogging and discoloration: Excess humidity clouds clarity, reducing shelf appeal for retail packaging.
Material deformation: When products are exposed to extreme temperatures (e.g., inside trucks or warehouses), standard shrink films can warp, tear, or lose elasticity.
Whether you’re shipping beverages across the state, wrapping seafood in a cold chain environment, or securing pallets outdoors, the film you choose—and how it’s applied—makes all the difference.
Sun Packaging helps companies across Florida identify the most effective heat-resistant shrink films for their specific industries. Below are the most common options and how they perform in hot climates.
Polyolefin (POF) is the go-to choice for most Florida applications. It combines strength, clarity, and flexibility with excellent resistance to heat and moisture—making it ideal for retail-ready packaging and consumer goods.
Key advantages:
Maintains strength in both high-heat and refrigerated environments.
FDA-approved for food contact applications.
Highly puncture-resistant, reducing waste during production.
Available in cross-linked versions for added durability and gloss.
Example:
A Fort Lauderdale beverage co-packer was seeing inconsistent seals and clouding during summer months. Sun Packaging helped transition their operation to a cross-linked polyolefin shrink film, paired with a recalibrated shrink tunnel system. The result: improved clarity, stronger seals, and reduced downtime—especially during hot afternoon shifts when warehouse temps peaked over 95°F.
PVC (polyvinyl chloride) shrink film remains a solid choice for light-duty packaging where visual appeal and affordability matter—such as printed materials, software, or boxed retail goods.
However, because PVC is more temperature-sensitive, Sun Packaging recommends modified PVC blends engineered for tropical climates. These blends maintain shrink consistency even when ambient conditions vary widely.
Best used for:
Lightweight consumer products
DVDs, cosmetics, and boxed goods
Retail gift sets
Example:
A Coral Gables cosmetics brand used standard PVC film that often warped during summer transport. Sun Packaging replaced it with a heat-stabilized PVC blend and fine-tuned the sealing temperature, eliminating the shrink distortion problem completely.
When strength and load stability matter most, polyethylene (PE) shrink film delivers. PE is thicker and more durable, making it ideal for bundling, pallet wrapping, and industrial packaging.
Key benefits:
Excellent tear resistance for bulk and heavy products.
Performs well in both outdoor and indoor storage.
Provides superior puncture strength for irregular loads.
Example:
A Palm Beach building supply company needed to secure large pallets of roofing materials stored outdoors. Sun Packaging recommended a low-density PE shrink film with UV inhibitors—protecting the product from both sun exposure and Florida’s humidity. This solution reduced product damage rates by over 40% within three months.
Even the best film can fail if your shrink equipment isn’t properly tuned for Florida’s climate. High ambient temperatures can throw off seal timing and tunnel temperature control.
Sun Packaging provides and services heat-optimized shrink systems from trusted brands like Texwrap, Shanklin, and 3M, designed for consistency in high-temperature environments. Our technicians help customers:
Calibrate seal bar heat and dwell time for summer conditions.
Maintain consistent tunnel airflow to prevent uneven shrink.
Integrate automation and film feed systems for higher efficiency.
Example:
A Miami snack manufacturer struggled with inconsistent seals during summer months. Sun Packaging audited their system, added ventilation improvements to their shrink tunnel, and installed a film rated for higher shrink temperatures. Output quality stabilized immediately—even during August heat waves.
Sun Packaging supports a wide range of Florida industries that depend on climate-tough packaging:
Food & Beverage: Protecting seafood, citrus, bottled drinks, and frozen goods from moisture and heat degradation.
Pharmaceuticals: Maintaining tamper-evident seals for temperature-sensitive products.
Manufacturing & Distribution: Securing bulk loads and industrial components for transport and storage.
Retail & E-commerce: Ensuring crystal-clear presentation and product protection during last-mile delivery.
In each case, Sun Packaging tailors its recommendations to the specific heat, humidity, and storage conditions of the client’s operation.
