Twist off closures have been used within the food and drinks industry for many decades and for many decades to come. Favoured with acidic and vinegar based products due to the rubber lining within the lid, both preserving freshness and preventing leakage. However with non tamper evident screw top caps and twist-off closures, once the product has left the security of your kitchen/ factory or restaurant your product is at risk of being tampered with. A risk neither you or your customers should take.
At Ampulla we are always trying to source new and exciting products, we also look for ways to help our customers provide the best product for their customers too and so with this in mind, we’ve looked at ways larger food companies tackle the above issue and our conclusion is something many of you will be already familiar with. Shop bought sauces, dressings, jams etc, you’ll notice many come with a protective plastic sleeve around the neck and cap, this must then be teared open before the cap or lid can be unscrewed. You would be right in thinking this process would be done at the manufacturing stage once the product has been mass produced and filled, and you are probably also thinking, that’s good for them with all their big machinery and manufacturing processes but we are just starting out producing our product. What if we told you there’s now a product out there, that can be applied by hand without the use of heavy machinery, creating a tamper proof seal, and better still, this product can now be bought directly from Ampulla.
Trialling in a few pre-cut sizes, our shrink sleeve closures are in stock now. Made from wood pulp, seals are fully bio-degradable when discarded. Seals come in a protective container and held in a mild (Non harmful) preservative solution and are fully transparent once dried.
Shrink sleeves are applied to the bottle/ jar top and neck, this is done when they are wet and only one sleeve is needed per jar. Sleeves are then allowed to dry naturally, drying times can depend on air and container temperature and the shape of the container. Shrinkage usually starts within 10 – 15 minutes and within one hour most of the shrinkage will have taken place. Some bottlers will accelerate the drying time by using hot air blowers, but we do advise customers do so at their own risk.
Storage and handling
Do not allow the sleeves to freeze, or store them in minus temperatures, as this will weaken them. Rotate the container regular as this will stop the separation of the preservative solution. Please make sure the shrink sleeves are always covered in the provided solution to prolong their lifespan and to prevent drying out. Do not store the sleeves in water as this will remove the plasticiser and the sleeves will split after application.
