Hot Water Shrink Equipment for Vacuum-Packaged Food

Hot water shrink equipment tightens compatible shrink bags around vacuum-packed products for a clean retail finish. Available models include the ST-6050 hot water dip tank and the ST-8031/10065 automatic hot water shrink tunnel. Send your bag specification, pack dimensions and target output so we can confirm the suitable configuration.

How it works

What Hot Water Shrinking Does

After a product is vacuum sealed in a compatible shrink bag, controlled immersion in heated water shrinks the bag around the pack. The right water temperature and immersion time depend on the confirmed bag material, thickness and product dimensions. The result is a tighter pack with less loose film around the product.

This process is for compatible vacuum shrink bags. It is not a universal replacement for every vacuum bag, tray overwrap or hot-air shrink process.

Selection guide

Information Needed to Select the Right Configuration

Share the pack and production details first; the machine should be matched to the bag, not guessed from a generic model table.

Bag specification

Provide the shrink-bag material, thickness, supplier data sheet and sealing method so compatibility can be checked.

Pack dimensions

Share the finished pack length, width, height and product weight to confirm usable tank space and handling method.

Target output

State packs per hour and whether the process is batch or continuous. This determines whether a dip tank or a future continuous solution is appropriate.

Site utilities

Confirm electrical supply, drainage, water access and installation clearance before a final quotation.

Product and hygiene needs

Tell us the product type and cleaning routine, especially for wet, salty or high-care food applications.

Required documents

Specify your destination market and requested documentation. Available certificates and options are confirmed for the final configuration.

Frequently Asked Questions

01What is hot water shrink equipment used for?
It is used to shrink compatible vacuum shrink bags around a sealed product. The selected water temperature and immersion time must match the confirmed bag specification and finished pack.
02What is the difference between a dip tank and a continuous shrink tunnel?
A dip tank is generally used for a handled or batch immersion process. A continuous tunnel moves packs through a controlled process. The appropriate layout depends on pack handling, output and the confirmed shrink-bag requirement.
03Which bags work with hot water shrinking?
Only bags designed for hot water shrinking should be used. Send the bag material, thickness and supplier data sheet so compatibility can be checked before a machine is selected.
04What information is needed for machine selection?
Please provide the bag specification, finished pack dimensions, product type, packs per hour, site voltage, drainage details and requested documents. These details determine the appropriate configuration.
05Can ST-6050 be used for my product?
Suitability is confirmed from your compatible shrink bag, pack dimensions, handling method and required output. Please share these details before ordering.
06Which certificates and documents are available?
Tell us the destination market and the documents your project requires. Available certifications and configuration options are confirmed in the quotation for the selected machine.
