Palestine Action posted a video online of masked activists damaging and breaking into the Kite Packaging site in Sittingbourne, Kent, on Monday (8 July).
The video shows the building being daubed with spray paint, windows and doors being smashed, roller shutters being glued shut, and damage carried out to vehicles.
The slogan ‘Drop Elbit’ was spray painted onto the Kite building.
In a statement, Kite Packaging said its entire team was “shocked and traumatised by this attack”.
“As an employee-owned company, Kite has recently made substantial investments into the site at Houte Green, Sittingbourne trying to make a fantastic home for all our people.
“To have our investment and effort destroyed by vandals under the misguided impression they are helping the people of Palestine is truly frightening.”
Kite said the damage done to its building and vehicles would run into tens of thousands of pounds.
Palestine Action claimed that Kite Packaging provided materials used to secure and transport Elbit weaponry.
“The company’s complicity was confirmed when actionists broke inside Elbit’s Instro Precision factory in Kent last month, exposing numerous suppliers of the Israeli weapons maker,” the group stated.
The activists have been targeting Elbit because it supplies weaponry systems to Israel.
However, Kite said it did not have a customer called Elbit on its books “which makes this situation even more perplexing”.
“It is really sad that our honest and hard-working local employees now feel scared to come to work due to these events,” the Kite statement concluded.
Kent Police said it was investigating a burglary at the site: “During the incident several windows, doors and computers were broken, and spray paint was also used to damage the inside of the building. Enquiries are ongoing to identify those responsible,” the force said.
Kite supplies a wide range of off-the-shelf packaging materials, including boxes and mailers, tubes, void fill, and food packaging.
Its bespoke product range includes heavy-duty packaging for the aerospace, automotive and electronics industries.
The Coventry-headquartered business had sales of nearly £168m last year and employed around 400 staff across its operations.
