Antrim and Newtownabbey Police said they were called to respond to the fire at Stiles Way in the Rathenraw industrial area around 8:30 p.m.
Several local residents said on social media that they heard a number of “big explosions” from the blaze.
Roy Purvis, Group Commander, Northern Ireland Fire and Rescue Service [NIFRS], said 38 firefighters were involved in fighting the blaze, along with six devices.
He said it started in a single truck on Tuesday night before spreading to around 30 more trailers.
Jets of foam and water are used by firefighters to fight and control the fire.
Antrim and Newtownabbey Police have asked residents near the estate to “stay indoors and keep their windows closed due to the large amounts of smoke in the area.”
Belfast Live reports that at least one burning trailer contains plastic, which worries firefighters at the scene.
The blaze can be seen from afar with a number of images and videos circulating on social media.
A spokesperson for NIFRS said it was too early to establish whether the fire was deliberate or accidental.
The B518 Stiles Way was closed in both directions due to the fire in the nearby industrial area.
Police are calling on all people and road users to avoid the area while emergency services attempt to fight the blaze.
Residents living nearby have also been advised by police at the scene to stay indoors and keep their windows closed due to the large amounts of smoke in the area.
