About Our 5-Layer Thermoshrinkable Plastic Casings

We stock 5-layer thermoshrinkable plastic casings manufactured from PA/PE (Polyamide/Polyethylene) multilayer film. The 5-layer structure provides very good water vapor, oxygen, and UV barrier properties and can help protect product aroma, freshness, and shelf life, depending on the product formulation, processing conditions, packaging, and storage conditions.

These casings are thermoshrinkable. They shrink tightly around the product during thermal processing, producing an unwrinkled, smooth, professional surface appearance. Food grade plastic casing, manufactured using virgin PA/PE polymers suitable for food contact applications.

Plastic sausage casings in various colors

Available Formats

Shirred, compact shirred sticks for automatic stuffing lines
Non shirred cut lengths, for manual production
Reels, continuous casing on the reel for lines that cut and clip in house

A shirred stick is a pre shirred length of casing compressed into a compact stick, allowing the casing to feed continuously onto the stuffing horn during production.

Typical Applications

Cooked Salami
Cooked Beef Salami
Liverwurst
Bologna
Chicken Bologna
Chicken Sausages
Mortadella
Salchichon
Black Pudding
White Pudding
Ground Beef
Ground Pork

✅ This list is not exhaustive. Plastic casings are suitable for a wide range of cooked and processed products that do not require smoke permeability. Contact us at 201-939-3335 to confirm the right casing for your specific product.

Available Diameters and Size Chart

Plastic casings do not use size codes. You order by nominal diameter, available from 30 mm through 160 mm. The nominal diameter is also the stuffing diameter: stuff to the nominal diameter for a finished product of that size. If needed, the casing can be overstuffed by approximately 2% to 5%, which makes the finished diameter slightly larger, as shown in the chart.

Diameter, Circumference, and Lay Flat Width

Some processors measure a casing by circumference or by lay flat width (the width of the casing pressed flat) instead of diameter. These can be used as a reference, but the most accurate way to choose your casing is by the finished stuffing diameter. Circumference measured on the stuffed product right after stuffing, before cooking or further processing, is a reliable check. Heat processing can change the size, so a measurement taken after processing will not reflect the true stuffed size.

Diameter

Straight line measurement across the casing.
Example: 105 mm (4.13 in)

Circumference

Distance around the casing.
Example: 330 mm (12.99 in)

Lay Flat Width

Width when the casing is pressed flat.
Example: 165 mm (6.49 in)

Example measurements above are for a 105 mm (4.13 in) nominal diameter casing, flat and unstuffed.

About the lay flat and circumference columns: both are approximate guides calculated from the nominal diameter. Actual measurements can vary slightly, so use the stuffing diameter as your primary reference.

PE (Polyethylene), offers flexibility, sealability, and moisture resistance

Recommended Overfilling

Recommended overfilling is approximately 2%–5% for all diameters.

Soaking & Preparation

Soaking and preparation requirements can vary by casing size, format, and manufacturer. The following are general guidelines. Always follow the preparation instructions supplied with the specific casing.

Soak in running water at 20–25°C before use. Do not use higher temperature as this will activate thermoshrinkability
Soak evenly on the inside and outside
Minimum soak time: 30 minutes for non shirred cut sections; 60 minutes for shirred casing
Soak only as much as can be used within 4–5 hours
Change soaking water at least once every 12 hours
The casing must not contact any rough surface during preparation

Example Thermal Processing Schedule (Steam)

Processing conditions must be adjusted for the specific product formulation, casing diameter, equipment, and desired finished product. Follow your established validated process and the casing manufacturer's recommendations.

Step	Chamber Temp	Humidity	Duration / Target
Step 1	55°C	100%	15 minutes
Step 2	65°C	100%	20 minutes
Step 3	70°C	100%	30 minutes or to 60°C core temperature
Step 4	75–90°C	100%	10–15 minutes or to 72°C core temperature
Cool immediately	Cold water / shower	N/A	Until product core drops below 30°C

⚠️ After steam cooking, sausage sticks must be cooled immediately by running water, shower, or programmable sprinklers. Do not place hot sticks directly into the cold room. This will cause wrinkling of the casing surface.

Restrictions

Maximum processing temperature 90°C. Do not exceed
Not suitable for microwave oven heating
Not suitable for consumption, remove before serving
Stick weight should not exceed 4.5 kg for hanging treatment
Do not stack casing rolls without spacers between them
After disinfecting steam chambers with chemicals, rinse thoroughly before use, chemical residue can delaminate casing printing or damage the casing surface

Storage Conditions

Storage and conditioning requirements may vary by casing format. Follow the manufacturer's recommendations for the specific product.

Store in original packaging in a dry, clean, cool location
Storage temperature below 25°C, humidity 30–75%
Unpack directly before use
Keep away from direct sunlight and high temperature sources
Condition at 10–25°C for at least 24 hours before use after transport
If transported below 10°C, extend conditioning time accordingly
