Remarks

Our products and processes comply with the laws and regulations, including the International Code of Cork Stopper Manufacturing Practice and the Portuguese and European legislation for materials and articles intended to come into contact with food.

Packaging

They are packed tightly in LDPE plastic bags with 1.000 cork stoppers, under vacuum, with 0,5 or 1,5 mg/cork stopper of SO2, and placed in cardboard boxes with or without printing.

The amount is usually a box of 3.000 cork stoppers. The cardboard boxes are strapped and/or palletized (wrapped in stretch film). Small amounts can be sent without stretch film.

In the boxes or raffia bags is placed a label with the following information:

— supplier name, customer name, size x class;

— marking (if applicable), lot number, box number, corks amount per box, order number, and other information requested by the client.

When Lafitte Bartop is not responsible for the shipment, another label with the client’s address is placed.

Intended use

Bartop cork stoppers to close wines, liqueurs, and other alcoholic beverages with the bottle handling in the vertical position.

Validity

The maximum period that cork stoppers should be kept in stock after the treatment date should not exceed 4 months, in appropriate storage conditions.
This is because sulfur dioxide (SO2), used as an antiseptic and antioxidant, declines over time, increasing the likelihood of microbial contamination.

Transportation recommendations

Making the transport in a closed vehicle, clean, dry, and free of odours. Fluctuations of humidity during transport should be avoided.
Transportation must take preferably cork products, providing that they are free of odours.
It can be transported with other products since they are not toxic and are free of odours.

Storage humidity

The storage relative humidity must be between 40% and 70%.

Storage temperature

The storage temperature must be between 15 ºC and 20ºC.

Other storage recommendations

In the case warehouses don’t present values of moisture and temperature within the recommended ranges, the product should be checked before use.

The cork stoppers should be stored in a dry, clean, and ventilated place and insulated from floors and environments that can somehow transmit odours or flavours. It’s not recommended to use pallets treated with halogenated products – suggestion: heat treatment.

Disinfections should be carried out periodically to all materials that can be a vehicle of contamination. Avoid the use of disinfectants with chlorine.

Treated cork stoppers: once the package is opened, the cork stoppers should be used as soon as possible.If the cork stoppers are not used it is advisable to seal hermetically the bag that contains them and add to it a small amount of an antimicrobial agent such as sulfur dioxide - SO2.

After bottling, during the transport, storage, etc. You should keep the bottles stocked in a vertical position.
